Often, users of mobile gadgets running on the Android OS are faced with the problem of turning off the screen lock. A graphic key, password or PIN code is installed, but the owner of the device wants the protection to be removed with a simple flick of the finger, or the screen does not lock at all. Trying to simply go into the menu and remove the restrictions, the user sees that he can’t access the necessary options, because the necessary lines are inactive. This error has a fairly simple solution, and now I’ll tell you what needs to be done to remove the restrictions if these actions are prohibited by the administrator, encryption policy or credential storage.

Settings menu with the error message “Forbidden by administrator, encryption policy or credential storage service”

Why does the administrator ban error

In addition to the fact that mobile gadgets on the Android platform have built-in programs that ensure data security, many users install additional security features and, without knowing it, start administration or an encryption policy. As a result, the owner of the device includes such protection that he himself does not get access to certain settings of the tablet or phone.

Also, the error message “Forbidden by the administrator, encryption policy or credential storage” may pop up when installing any useful software that has a certificate that changes the settings of the mobile device. In this case, the application asks for permission to activate the device administrator, and if the user confirms the action, after the installation is completed, a message pops up saying that the administrator is activated.

Admin Activated

The third reason is corporate security policy. That is, if with the help of your device you get access to the information of the employing organization and your e-mail box is remotely connected to the company’s network, the error may be due to the actions of IT specialists. In this case, before solving the problem, you should contact them and together try to eliminate the error “Forbidden by the administrator, encryption policy or credential storage”.

How to fix the “Forbidden by administrator, encryption policy or credential storage” error

If the problem arose after installing an application that provides additional protection for the device, then if this program is not needed, it must be deleted. If you do not want to delete the application, you can disable the administrator so that no extraneous programs can control the phone. To do this, in the gadget settings you need to go to the security menu and go to the “Device administrators” item.

Device administrators

If there are any programs in this menu, especially unknown to you, you need to click on their name. If a message pops up that the administrator is activated and allows the application to lock the screen, this means that you need to remove these rights from this program - uncheck the box or move the button. If necessary, you can again go to this menu and again give the application the right to lock the screen.

Programs in the Device Admins menu

The next step is to clear device certificates that do not allow to reduce the degree of security of the device. The desired item is located at the very bottom of the “Device Administration” menu. Depending on the gadget, it’s called “Clear credentials” or “Clear certificates.” In both cases, the same action is assumed - the removal of all certificates. Select it and confirm the action.

Certificate Cleanup

If you are afraid that during the process of certificate deletion you will lose personal data, back them up. You can send important files to the cloud, and then download them again to your phone. Nothing bad will happen to the device itself. A big plus of Android OS is synchronization with your Google account. In this case, all contacts are stored on the cloud by default. If in doubt, check the synchronization. To do this, go to the “Accounts” or “Accounts” menu in the settings and click on Google. There you will see all the necessary information.

Google Account

For normal operation, restart your smartphone or tablet, go back to the security menu and check if lines previously containing the error message “Forbidden by administrator, encryption policy or credential storage” have become active. If so, feel free to turn off the screen lock or activate a simple unlock with your finger.

This method should give the desired result - unlock inactive fields. If this did not happen, then the last option is to reset to the factory settings. Before performing these actions, save important information: personal photos, videos, files necessary for work, since when resetting, all data will be lost.
