The mobile interface for this application is pretty much the same as the browser addon - it is meant to be used, and is not necessarily the best for performing administrative functions.

NOTE: For your own protection, mobile apps don't let you take screenshots.

Installs

The applications for Apple and Android are available in the App Store and Google Play respectively.

Note that for Android, the application is also available in the F-Droid repos: https://mobileapp.bitwarden.com/fdroid/ 

Unlock Options

For the initial login, your master password is of course required as it generates the data necessary to retrieve your passwords. However, after the initial login, you have the option of unlocking the application simply with your biometrics or your PIN.

It is recommended to set it to one of the above, since it would get extremely tedious to continuously be required to insert your master password every time that you want to auto-fill a login.

Auto-Fill

The autofill will pop up once you enable it in the settings. The following prompt pops up whenever you click on a password field. This is an example of logging into ebay on a mobile browser:

From there, it will switch apps to your Bitwarden app, where you can select the application to auto-fill it with. Keep in mind that the auto-fill follows all of the rules of the browser add-on.
