Without your Master password, you will be unable to access your Passwarden account and view or edit the stored data. However, if you forget or lose your Master password, you can recover it. For this, when first creating a Master password, you will also receive a recovery kit - a file that you can download or save. Inside, you will find all the information you need to recover your Master password or create a new one. Learn more about how to change or recover your Master Password.

If you tap the Tap to unlock label and nothing happens, please perform the following actions: 

Go to Settings > Apps > Manage apps.

Print Passwarden in the Search field, open its info, and select Other permissions.

Allow Display pop-up windows while running in the background, and that’s it!
