[Q] Knock Code option disabled/grayed out - G2 Q&A, Help & Troubleshooting

On my Sprint LG G2, the option to select the screen lock setting of "Knock Code" is disabled/grayed out with the following message:
Disabled by administrator, encryption policy, or credential storage
(the options to select "None", "Swipe", and "Face Unlock" are also disabled/grayed out)
Any way to figure out what is causing this, and to correct it?
Thanks!

Two options come to mind:
Is your device encrypted?
Do you have maybe a connection to a corporate Exchange server? That may be adding device policies.

go to setting - security - certificates management - clear credentials

API for enable/disable device lock ?

anybody knows if API exists to disable or enable device lock? I'm not talking about the security policy, but the one that could check or uncheck "prompt if device unused for" ?

6.5 lockscreen?

I have 6.5 on my HD and was curious if I could use the lockscreen but without a password so I could keep the slider and notifications, I just dont want to enter a password each time thanks!
the only time you have enter the password, is if you setup the pin function on it, otherwise the slide fuction in wm6.5 works as normal

Forced lock by MS exchange
Yes this is a huge problem. I have the pin lock force on by MS exchange security settings. In WM6.1 this only affecxted when the phone was turned on not everytime it is locked.
This cab (from another thread) removes the lock enforced by Exchange.
Works on my 6.1 and I believe on 6.5 too.
Run it, then go to you Lock settings and the tick box to remove lock is no longer greyed out ...
Alternatively here's the reg setting to edit:
Enable/Disable Exchange Security Policy
Registry Key: HKLM\Security\Policies\00001023
To enable it: Set value to 0
To disable it: Set value to 1
I used similar registry tweak in WM6.1 to get away with the exchange security policy but not working now for the new WM6.5. eg. I can change the inactivity minutes AEFrequencyValue to long enough but still the phone asks for unlock password frequently.

I have the Same Problem.
I'm force to have a Password from the exchange security Policy.
I have set the "Promt if phone unused for " to 30 Minutes, but each time the the phone goes to sleep, the Password is asked again.
Did someone have a solution without disabling Exchange Policy or installing S2U2??
Thanks

If you disable lock in setting > lock, i.e. untick 'Prompt if phone unused for' and just use slider functionality in wm6.5 you don't need to enter PIN any more.
Install attached cab (Smart Lock) and once installed go to settings > system > smart lock and ensure that both 'wm6.5 new lock' and 'suspend lock' are ticked, then soft reset. Now each time you turn screen off device will lock and to unlock it you use the slider
I installed the Stay Unlock cab and I still have to enter my password when my phone reboots. Until now, for day, it did not ask me for a password after 15 mins of inactivity, but today, it is again asking me for passwd every 15 mins if I don't use the phone. I am not even able to ever uncheck the setting for Lock which turns on requiring passwd - that setting is grayed out for me even after installing the cab. Could someone please throw some light on this? Thanks.

==========================
in 6.5 the key is a bit different (policies twice):
Enable/Disable Exchange Security Policy
Registry Key: HKLM\Security\Policies\Policies\00001023
To enable it: Set value to 0
To disable it: Set value to 1
WM 6.5 Company Policy Activated Device Encryption
I recently set up Exchange e-mail on my WM 6.5 AT&T Tilt 2 (Touch Pro 2), which resulted in activating device encryption. Although I check the email box to remember my password, the device constantly asks me for a password.
I've since removed the Exchange e-mail account (I'll go back to synching rather than direct connect as this is too much of a hassle). However, I can't seem to turn off device encryption.
After reading this forum, I've tried the "Stay Unlocked.cab" and the registry settings (e.g., HKLM\Security\Policies\Policies\00001023 setting) to no avail. The "Prompt if Phone unused for remains grey/unselectable.
One thought: When I checked the 1023 key setting it was 0 so I set it to 1. That had no effect. But reading the post 0 = enable so I tried setting the value to 0 and got a message popup: "Exchange server has just enforced security policy required for Active Sync." So something of Exchange is still running or enabled...how can I turn this off?
WM 6.5 Company Policy Activated Device Encryption
Deleting the Exchange connection in Active Sync did the trick. That was so easy I do feel a bit foolish...

[Q] Security questions

I have had my Nexus 10 for about 2 months now, and I have always had the PIN options for unlocking the tablet. However, I am now trying to get rid of security but when I go into security under setting, I am unable to select:
None
Slide
Face Unlock
All three are grayed out and it says "Disabled by administrator, encryption policy, or credential storage". I've been looking around settings and can find no way to fix this. I have no trouble picking the other three options, pattern, PIN or password, but and have no idea why those 3 are grayed out.
AW: [Q] Security questions
Probably because you use either a certificated WiFi connection, VPN or a similar connection you had to setup first. Some connections require a PW to bet set to ensure authentification

Go to "Settings > Security > Device Administrators" and check if there are any administrators defined and checked there.
Admins

It says no available device administrators. How do I change that?

You don't want device administrators. aritrea's post is likely the answer to your question.

[Q] Credentials issue - lockscreen set to "slide"

There's this issue that's really bothering me. When I create a VPN connection system asks me to create a code (pattern, pin or password). Then, lockscreen requires my code to unlock, and it doesn't allow me to change lock back to none because, it says, it's protected under a credential storage.
If I clear my credential storage it clears my saved connections.
Now I found an app that disables lockscreen without deleting the credentials, now even though "none", "slide" and "face unlock" are greyed out, option is set to none. Too bad I want "slide", not "none". But in this case should be simpler..

[SOLVED] VPN Client, Credential Storage Password Prompt

I tried to add a new IPSec VPN profile today and after saving the preshared key I was prompted to enter the Credential Storage password, which I have never setup. Anything I enter fails; I can keep trying indefinitely and it never prompts to reset credential storage.
Looking in Settings > Security > Credential Storage shows Storage type is "Backup to hardware" and not changeable and Clear credentials is also grayed out.
Why can't I create local credential storage secured by my own password with this device?
EDIT: So I found the workaround, but not really an answer to the credential storage issue:
http://www.pocketables.com/2014/02/fix-credential-storage-roadblock-android.html
Essentially, Credential Storage forces you to use PIN or Password unlock options only, but you must disable all unlock options first and run something that requests credential storage to enable it. If you set PIN or Password unlock yourself and try to enable credential storage in VPN it will fail. Thankfully I don't need to use VPN from device really so i can go back to Fingerprint unlock, but hopefully this helps someone else in the future.
I've tried it repeatedly, all with same results. Not sure how to resolve it yet

By the way, I brought this issue to both Samsung and Verizon support and their only answers were to perform a factory reset.
Lesson learned: I'm better at supporting my device than the manufacturer and carrier combined.
