I forgot my application start up password for eM client, what do I do?

Hello Eric, unfortunately if you’ve forgotten the master application password, there’s no option to recover it as the password is only stored in your offline database. You can remove the current database in order to force the application create a new database allowing you to setup your accounts from scratch.

Navigate to your local user/AppData/Roaming folder and remove or rename the eM Client database in order to create a new one on next application startup.
