I was trying to set up a VPN connection on my Android device the other day and I was asked to enter a credential storage password. I couldn’t remember what the password was and I couldn’t even remember setting up one. I kept trying different passwords till I got a message that the credential storage had been cleared.
I was able to setup the virtual private network but before that, the device asked me to set up a passcode. I did. After doing this, I realized I couldn’t disable passcode lock any longer. The other security options like face unlock too were grayed out.
- Go to Settings > Security
- Scroll down till you see Clear Credentials.
- Tap Clear Credentials and select OK to confirm.
You should see a message displayed showing that the credential storage has been erased.
By now, if you try going back to your security lock options, those grayed out options should now be properly displayed and selectable:
This is quite an easy fix to a problem that looks rather complicated.
