Issue with lockscreen

I recently had to add my corporate email account to my S3. I was required to add a PIN or password, which I wasn't real fond of, but I understood why so I did it.
Now, having been issued a work phone, I do not need my email on my personal device anymore so I removed it. However, I cannot remove the need for a PIN/password.
If I go into my lock screen settings and attempt to change to a different unlock type it notes that they are disabled by administrator, encryption policy or credential storage.
As a result I have removed all applicable device administrators (minus Tasker and Cerberus), cleared device credentials and removed my SD card as it notes that it is encrypted.
All of this has been to no avail as I still cannot change my lock screen type. Any suggestions on what is causing this issue? I asked our IT company and they said "Call Verizon." Um.... thanks?
Thanks for the input guys!

Bump. I would hate to have to wipe my phone to fix such a silly issue.

Halp.

Did you install something called device policy? We had to do this through our school email in order to be able to get our email on our devices. I also had the problem of not liking a security lock screen so I removed it. I don't know if this helps or not, but here are the steps, according to my school ITS website.
On your device, go to Settings > Security
Press Select device administrators
Uncheck Google Apps Device Policy
Press Deactivate.
Go to Settings > Applications and click the Google Apps Device Policy app
Press Uninstall to remove the application

I appreciate the input by unfortunately did not have Google Apps device policy under my device administrators or installed applications.
I was however able to fix this by going to Settings > Security > Encrypt external SD card and unchecking encrypt. I was only allowed to uncheck this value after creating a 6 digit password though.
Hope this helps somebody. Thanks!

[Q] Unable to Unlock (TF700T)

Hi All,
I've been doing a lot of searching and reading on the forums but haven't found an solution to my problem.
I've been tgrying to unlock the boot-loader of my tablet for days. I downloaded and installed v8 of the
ASUS unlock tool.
Everytime I try to use it, I get to the "Google Account Verification" step it says:
"Your password is not valid"​
I know I've entered the correct password. I've actually signed out of my google accounts from the tablet
and then signed back in just to make sure I wasn't fat-fingering it over and over.
Here're the details:
ASUS Transformer Pad TF700T
Android Version 4.2.1
Kernel Version 3.1.10-gb1a9af5
Build number: JOP40D.US_epad-10.6.1.14.10.20130801​
As far as I know, the tablet is absolutely stock (I bought it on e-bay)
If someone could point me in the right direction, I'd really appreciate it.
I want to unlock, the install TWRP via fast-boot on the way to trying a couple of custom roms.
My search-foo is relatively weak so if I've missed an obvious thread, please forgive me.
atTHANKSvance!

You don't have 2-step verification activ on your Google account, do you?
If yes, you need to disable it for this procedure.

Brilliant!
You have almost certainly diagnosed my problem....
It's late here, but I'll turn off 2-factor authentication and try again in the morning.
I'll post again with my results.

That was my problem..
I didn't actually need to deactivate 2-step authentication. Google will generate an application specific password for those programs that can't handle the 2 step process. I generated one for the unlock tool and it unlocked on the first try.

That was it...
Instead of deactivating 2-step auth, I generated a new app specfic password for the unlock tool. I put it in and it worked the first time.
Thanks again!!

I actually didn't have 2-step authentication activated...BUT...after reading this, I tried generating an app specific password for the Update tool, and worked for me. Thanks for the tip.

Here's another solution: (I couldn't get any of the above solutions to work)
After 20 minutes thrashing around in the jungle of Google settings I discovered that in the Google "Less secure apps" page of the account settings it says "Some apps and devices use less secure sign-in technology, which makes your account more vulnerable. You can turn off access for these apps, which we recommend, or turn on access if you want to use them despite the risks." So I changed the "Access for less secure apps" on that page to "Turn on" and - bingo ! - the Unlock app on my Asus tf700t accepted the Google account password that it had previously been rejecting and went on to unlock the tablet. Then I went back to the "Less secure apps" page of the account settings and changed it back to "Turn off", i.e. I restored it to the more secure setting.

I have tried this as well and I cannot get my tablet to unlock. I have verified it is registered within ASUS' systems, I have verified I do not have 2 factor authentication and I have less secure access on.
Does anyone have any other ideas how to get passed this Google Password issue?

Yes. Factory reset the tablet, setup wifi but no Google account, run the app, it'll work now

I found that once I deleted my Google account on the tablet I was able to complete the bootloader unlock.
Thanks for the assistance.

I've been trying to unlock mine for over 2 years. V7 unlock installed, removed account, ran unlock tool, VIOLA! Success!
Now, what seems to be the best ROM to use is what I have to figure out next...... is there a solid KK or Lollipop ROM?

Unable To Remove Lock Screen/PIN

I'm not able to disable the PIN (or any security based lock screen; Password, Pin, or Pattern) and set the phone to just "Lock Screen" or even "No Lock Screen." The Face Unclock feature is also not available.
How do I remove the PIN (without a factory reset?)

Are you connected to a corporate Exchange email account? If so, I think the Exchange admin can require the lock screen and not let you turn it off.

+1 This happened to me on my last phone, built in policy in MS Exchange. I think if you delete the account, you can get the options back.

Only company email account used on the account is accessed through Gmail.
The "Lock Screen" was the selected option, until I tested out the PIN. But then when I went back into setting, Lock Screen and the other two were greyed out. So I can't remove the PIN now.

Only company email account used on the account is accessed through Gmail.

It's because you locked the microSD card. I had the same thing right now with LG G2 Mini

See if any of these will work for you
http://en.miui.com/thread-5684-1-1.html

it's for rooted devices and I'm not rooted. just delete the micro SD protection

How do you delete micro SD protection? Can this be done without formatting the card?

Of course, because you do not format it. Settings/security/decrypt SD card storage.
of course that option will be shown if you encrypted the card before
I think that also works with phone encrypt so maybe that's why you can't delete pin

Did you ever solve the phone lock problem?
I have the same problem as the one you've described in this thread. Did you ever come to a solution on this one?

Ditto. Clear certificates.

figured it out
I managed to sort the issue out by clearing the credential storage on my device. It may not solve the issue for everyone.

So I had this problem but only after this most recent update beginning may. And what I did was go to setting, then security, there should be a credential storage area. I cleared the credentials went back to lock screen and it wasn't greyed out anymore. I don't even know what activated this because all I did was add a pin just like you and then wanted it off and I couldn't. But I solved it. Hope it works for you. Good luck

To opt out, Go to Settings » Accounts» Remove Google and Corporate/Exchange account then restart device.
Now again go to Account and add Google account.
Now lock the phone and try to unlock with invalid PIN/Pattern for 5 times, next it will automatically open SnapView settings, there, remove SnapView.
That's it, Go to Security » Lock screen, enter the current PIN/Pattern, now it will display all other lock options....
100% working for Android Lollipop, others not sure!!

Lock screens disabled by administrator?

I recently switched from the regular 3 way slide lock screen to a PIN unlock. I only intended to do this briefly, just to keep people from messing with my phone while it was charging. Anyway, when I tried to switch it back I found that the options Lock Screen, No Lock Screen, and Face Unlock were grayed out with the message "disabled by administrator, encryption policy, or credential storage". I didn't make any changes to any of those things (unless I did it unknowingly) so I'm not sure why this is happening. I'm running non-rooted stock Verizon Sense 6. Anyone else have this issue or know how to fix it? I like being able to have an easy lock screen most of the time.

Check your device administrators. It's under settings/security. I know foxfi forces this and some email apps too.

The only device administrator I have is Android Device Manager. I've tried unchecking it and rebooting, but I'm still locked out first three lock screen choices.

I had the same issue. I deleted my VPN profile, then was able to disable the lock screen.

I'm not sure that I have a VPN profile. I do use an Outlook client app for my work email. Supposing that I unknowingly have a VPN profile set up, how would I go about deleting it?

Virtual Private Network is used to connect directly to a private network. VPN may be needed in order to communicate with your companies email client. The settings are located in Settings>More>VPN.

My VPN screen looks like this. It must be some other issue. I imagine we'll be getting a firmware update some time in the next few months, hopefully that will resolve this.

Hope this works for you too.
I faced the same problem with my HTC One M8, and here is how I solved it for myself.
Go to Settings
Under Personal select Security
Scroll down to Credential Storage
Select "Clear credentials (Remove all certificates)"
Once this is done, I managed to gain back the first two options of "Lock Screen" and "No Lock Screen".
Hope this helps you!

Thanks alot

Clearing the credentials solved this problem, and I could erase my password.
Good luck for everyone

Why can't I shut off the lock screen security?

On stock 5.01. I have it on pin unlock right now but the options to shut it off are greyed out. The only other time I have ever seen that is whenever encryption is enabled which I do not have enabled, why can't I remove it?

Just tested on mine. I set and pin and then removed it. Do you have an app installed that set an administrator level policy on the phone? Under security-device administrators.

I believe that will also occur if you have an exchange email setup and exchange requires it.

Do you have a VPN configured?

Hmm ok. So I went through and deactivated all administraters but still "no lock screen" is greyed out.
No I do not nor have ever had an exchange account or anything other than just gmail.
As far as VPN I do not have one configured. I DO use super free VPN from the play store occassionally, but it hasn't created a noticeable VPN profile in my phone or anything. You have to run the app to even use it, and it gives you absolutely no info about what encryption tech it's using or anything else.
Just a side note, my phone is virgin 5.01 meaning it came straight from the posted ruu and wasn't upgraded from KitKat.

Just an update. Not sure what fixed it but I clicked on "clear credentials" under Security and instantly worked. Figured I would update in case someone else has the same problem!

That is the answer. Next time I looked it was back to the same state so it must be some sort of feature to make it hard on purpose.
