Enable bootup password - Google Pixel 3a Questions & Answers

Hey, I just got my 3a and I'm a bit surprised that I can't set a bootup password. That means that you have to enter your lockscreen pin/pattern/password for bootup to continue and to be able to decrypt /data. Or am I just not realizing that it's there since you don't get asked if you want to use it and after a restart there is a lockscreen panel, that at least looks like a normal lockscreen and not like the typical black screen with your keyboard to enter the bootup password but could actually be what I'm missing?
And of course we do not have TWRP yet so I can't just boot it and see if it asks me for the password to mount /data

After a reboot your device's data is encrypted until you enter your password. That's why you can't use fingerprint unlock the first time you reboot.

Ah thanks, so it just looks like the normal lockscreen while still doing the same thing as that black screen with an input field and a keyboard

[Q] Extend Lock Time on Encrypted Phone

Since i encrypted a phone, i have to enter PIN every while and then. Is it possible to remove screen lock?
OR
at least extend lock time to more than 30 min? I have ICS stock, rooted.
p.s. market apps are not working for encrypted phone, have tried all...
When I ran encrypted I could not find a way to go longer than 30 minutes before auto lock. Its more secure though.

true but i dont need it, before i didnt used lock screen at all, 2 hours would be enough...
Do you find a way to not enter password every time you want to unlock it?
I'm looking for the same, i want to enter pass only on boot, and then unlock normally.

New to HTC, encrypted at startup?

Hello,
I received my A9 yesterday. So far so good. I have a question about power on. I have never seen an Android device behave this way.
At power up, I get a padlock symbol on the screen which is unlocked. I bought the unbranded unlocked phone, so I assume that's a reference to my device being unlocked. After that screen I get a screen asking for my password.
"Your phone is encrypted"
"To decrypt your phone enter your screen lock pattern"
Is this something unique to HTC or the A9? I saw something that this may be different for rooting, but any information regarding this screen would be appreciated.
Ken
I'm waiting for a response to that exact same question. I also received my unlocked a9 yesterday.

I believe this is a result of marshmallow full-disk encryption and starts happening after you setup security on your phone. Remove security and you should no longer get this screen.
I just installed all my apps. and it did a restart. now its asking for decryption pw.
WTH!
is there a default?!

Just use the pin/password you used when you set up your device security. Once you enter it, you'll bypass the lockscreen and go straight to your home screen.

Thanks, I tried to get cute during set up and use a newer pin. I feel stupid. Thanks!

Understandable. New device. New pin.
Anybody knows how to avoid having to enter a PIN every restart, but do want PIN (or fingerprint) to unlock?

Just wondering, but what's the difference between entering your pin at boot versus at the lock screen? On boot, you still only enter it once.

First of all, with this phone I never have to even see the lock screen. I don't have to enter my pin or even push the power button to turn the screen on. I just need my finger. Also, sometimes I restart my phone and put it away to do other things. Now I have to wait until the phone restarted and only after I entered the pin I could put it away or it'll get stuck waiting for it forever.
Just wanted to add that on the Nexus, there's a way to set this up. You can have a PIN protecting your lock screen (and use fingerprint to bypass that) but not on restart. I could not figure out how to do it with this phone.
On that nexus, is full disk encryption enabled? The reason it prompts for your password before booting is because the entire disk, including the OS, is encrypted with your pass. Older devices which cannot decrypt on-the-fly without a noticeable performance hit won't offer full disk encryption. FileVault on OS X is another example of this type of encryption. With FV enabled the user is prompted for their password twice when powering on their computer: once to decrypt the drive and once again after its loaded to login.

One allows the device to read and boot the OS from the encrypted storage, the other simply grants access to the user to use their phone. The screen that is shown initially is stored in a separate unencrypted portion of the storage, it's kind of like a bootstrapper to the actual OS.
I think that encryption is mandatory for devices with Marshmallow preinstalled.
All devices that comes out of the box with Marshmallow will have it.
Unfortunately

I'm just curious why the Nexus (6P, in this case that I read somewhere else) allows the user to bypass this 'pin at restart' and still have the lock screen protected with a pin. Unless what Kardon403 said below is the answer.

Frankly, I know very little of the technicality. What you explained makes sense, although I'm still curious why this other guy with a Nexus 6p can have the 'pin at restart' disabled. It may mean that he set his phone to not fully encrypted?

I think he was simply wondering why it's a big deal for me to not enter my pin on a restart, while I have pin protection setup and would have to enter my pin when I unlocked anyway, in which case as I answered above, no I actually don't have to enter my pin to unlock the screen, because of the finger print sensor.
Anyway, this isn't really a huge deal, as for me it's simply don't put the phone away immediately after restart, but wait a little bit until after I entered the PIN. I was just curious.
When I first setup my device it was asking for the passcode on boot. Now I can power off and back on and reboot and it doesn't prompt. Has the phone become decrypted?

ArsTechnica on Marshmallow Encryption
I'm not sure exactly how full disk encryption is implemented, but it does appear that there is a way to disable the request for pin during boot:
It turns out that you can turn off PIN on boot but it's enabled by default and it's not obvious how to do it. You have to turn off the PIN (set your security type to None), then re-enable a PIN. At that point it will ask you if you want a PIN on boot or not.

Yes, those are the exact same instructions I found yesterday, but it doesn't work on this phone (One A9). When I reenabled the PIN, it didn't ask me whether I want a PIN at boot or not, the option simply says (something like) "enable PIN to unlock and boot".

Ah interesting. If I had to guess, this is an attempt by HTC or Google to enforce full disk encryption on our device because the 617 supports ARMv8 accelerated AES decryption . From what I understand, full disk encryption has been planned for a while but is getting pushed back from OEM and users due to the performance hit on devices without any AES acceleration. Ensuring that PIN at startup is enabled is the only way I can see to truly secure the entire contents of your phone's storage. I would think disabling this would circumvent a significant layer of security, it may even be disabling the encryption of the OS partition.
It appears that last years Nexus 6 takes a significant performance hit with this feature enabled:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is largely because the SD 805 in this device does not support ARMv8 (which offers dedicated instructions for AES encryption).
With 6.0 and the finger scanner it is enabled by default, you can not use the finger scanner and turn off the decrpytion but that requires a hard reset
Wow, I didn't know this would lead to such a great discussion. Thank you everyone for your input.
Phone Encrypted Mandatory? Restart Pattern Mandatory?
It seams that the HTC A9 gives you only 2 options:
1. You keep you phone with no security at all (no Patter, no Fingerprint, no pin)
2. FULL Security whit encryption.
The problem is that the option 2 makes my phone encrypted, and every time I restart my phone or turn ir on I have to enter the Pattern just do that the phone can start. I do not like these because when I restar my phone or turn it on i like to do it and put it away or on my pocket, I dont what to have to wait to enter the patter, ant it takes a lot jut to start the phone.
If these is the work of HTC or Android why did´t they gave us an option in between? security buy no encryption?
attached ar some images in the order of appearance when I restar/turn on my phone.
Have anyone solved theese issue?
thanks.

Lock screen pattern changed on its own, possible bug

I unlocked my phone normally several times today using my pattern. Five minutes after I had unlocked it, I picked it back up and drew my pattern and it said it was incorrect. I tried several more times with no change. I was able to unlock the phone using my fingerprint, but I have no idea how my pattern changed without my permission. If my phone dies or restarts for any reason, I will need the pattern to unlock it, as you can't use fingerprint on start up. (I've had the same unlock pattern since my last phone, so I'm sure I am putting it in correctly.)
Has anyone else encountered this bug? Is there any way to create a new pattern using my fingerprint? Finally, how should I go about reporting this to Samsung?
Thanks.
Yes!
Same thing happened to me... S7 working great for first few days when suddenly it didn't accept my unlock pattern. I've been using the same pattern for awhile and unlocked the phone a few times that morning. After a few reboots it finally accepted my pattern again. Immediately disabled it and now using pin instead.

Did you just restart again and again until it worked? If it worked for you I might try it instead of the factory reset.
I've had lock screen issues with my LG V10, but not quite like yours. I use a pattern, not a password or fingerprint. Sometimes the screen is locked and I fail the pattern and the phone gets unlocked anyway. Usually, this is associated with having first touched a notification with the screen locked. What happens after the pattern fails (trace shows in red), is that the screen appears as it does when it's not locked and I just swipe and I'm in the application whose notification I touched. The LG V10 has a fingerprint reader on the power button, but I haven't programmed it since I heard it's not that great. This is a major security issue in my opinion, and I haven't read any other posts anywhere about it. So I don't know if it's specific to LG, the V10 or Marshmallow (it started with Marshmallow).
I can start a new thread if you believe our lock screen problems are unrelated (enough). Just let me know.

Same thing happened to me. I'm THE ONLY one to ever use my phone and I went to open it and it was saying my pattern was invalid. I was able to use the thumb print pattern still though. However when I went to change the pattern in my settings I entered what used to be my pattern and it locked me out of my phone for an hour. I don't know how to change it.

Saw you had the same issue, so wanted to let you know. I restarted the phone and the old pattern started working again. Another person with this issue said that they had to restart several times, but it did work. So I'd give that a try, worked for me. Good luck!
It just happed to me. I restarted it and it accepted my pattern. I now have it set with pin instead.
Had the same issue as well! Samsung Galaxy S7, suddenly stopped recognizing my screen unlock pattern. Same solution as well; Restarted my phone and the problem went away.
Is there a way to disable the pattern feature if you are able to navigate the phone? Got locked out of Marshmallow on my MOTO G 3rd gen. phone after a pattern change; I was surprisingly able to just reboot into an unlocked phone. I've turned on adb debug access while I still have the opportunity.
I just had that issue. I was able to unlock with the pin, and reset the pattern and it now works again but it was freaky.
Same happened here. This morning the lock pattern on my S7 edge is forgotten by the phone.. Reboot doesn't help.
have the same problem today. i didn't change my pattern and it happened again. before i was using a PIN and I ended up factory reset and by this time I wouldn't want to do the reset factory settings as the last option.
The pin was also randomly stop working, I have mine set to pin and it did the same thing.
Me too!!!! Wtf!!
Mine has locked as well and I swipe the wrong pattern until it gives me the option to put in the back up pin but when I go to correct the swipe it wont let me in. I have tried everything all of you have suggested except the factory reset, I just can't believe that Samsung hasn't put out a fix for this yet.
Here is how you fix it
Method 1. Use 'Find My Mobile' feature on Samsung Phone
All Samsung devices come with "Find My Mobile" feature. In order to bypass Samsung lock screen pattern, PIN, password and fingerprint, you can just follow the below steps to get it done.
• First of all, set up your Samsung account and log in.
• Click "Lock My Screen" button.
• Enter new PIN in the first field
• Click "Lock" button at the bottom
• Within few minutes, it will change lock screen password to the PIN so that you can unlock your device.
tell me it work ??
Just an update to help out someone who might be going through this. This recently happened to me on my s6 edge.
Like the above comment suggests, go to "Find My Mobile". Once signed in, select the "UNLOCK MY DEVICE" option , (selecting the "Lock My Screen" option does not allow you to change the lock screen type afterwards).
Selecting Unlock my device will immediately unlock the phone and erase any lock screen patterns, fingerprints or pins that you might not remember, thus allowing you to set them up again!
Hope this helps!!

Also, one more thing. Doing the above ^ seemed to have solved a problem I was having with "Smart Lock" not working. So just as an FYI, going through that process might help you with that.
This just happend to my gf's s4 also she sent a text and then went to reply again a few moments later and her pin was invalid and it locked her out of her phone for 30 seconds, she just had to restart it once and it worked with the old pin again.

same issues here, pattern just stopped working. im positive im using the correct pattern.
i can login with my pin, but i cant reset the pattern as it keeps asking for the current pattern.
how can i reset the pattern or change to pin / fingerprint?
ive restartted 2x and trying a 3rd now....
> Use 'Find My Mobile' feature on Samsung Phone
No this didn't work. It still requires my pattern, and tells me I'm doing it wrong...
It DID let me into the phone, which was nice. But the pattern problem persists...
...Update: I restarted the phone, and it came up and accepted my pattern.
This just happened to me on my phone and my tablet. I wound up having to do a factory reset on both! Way to go Samsung. These are the last Samsung devices I'll ever buy.

Unlock screen behavior with fingerprint

Phone is on latest 6.01. I setup fingerprint to unlock and a backup password as required. Sometimes, it will ask for password instead of fingerprint to unlock. Another issue is sometimes it asks you to swipe up before you enter the password.
Usually right after I turn the screen on, I'm able to enter the password or fingerprint unlock on previous versions. Is this a bug or can this behavior be disabled? I just want to unlock with fingerprint in one step, makes no sense to have to swipe first then enter a password.

Password on an unlocked phone?

Stock Android One - 9 (MiA1)
So I had a password on my phone and a fingerprint lock. I used the fingerprint lock to unlock the phone and on restart it would ask me the password. All was good.
At some point I removed the screen lock altogether. I don't have a screen lock now and I'm able to enter the phone without prompt just fine even on boot,
Except, now I want to enable the screen lock again and it asks me to re-enter the password. Now the old password doesn't work and I could swear I didn't really touch it when removing the screen lock.
I'm able to do everything on my phone, except setup a screen lock. What is up here? And how do I setup a screen lock now or reset the password?
Not sure of the fix.
I got locked out of a PC bios like that ie the password spontaneously became corrupted.
I set passwords for accounts only, not devices and this illustrates why.
It may indicate a hardware failure or maybe just a firmware glitch. See if there's a default password for that model... a service center may be able to help.
