We have just rolled out Enpass Beta version 5.4.0 for Traditional Windows. It comes with some cool and most demanding feature like Quick PIN unlock, Auto backups and much more. Check out the complete changelog here:
Quick PIN support: Gone are the days when you had to enter the master password at every unlock of App. With this release, you can now set an alphanumeric PIN to quickly unlock Enpass if the App is already running in background, otherwise master pass
Sorry for the late reply. Once Automatic Backup is enabled, Enpass starts taking backups automatically to ensure that all of your changes are preserved. It will create a backup once some specified conditions are met with the Changes. But by the day end, it will keep save maximum of 2 backups in a single day and 60 backups total. We are working on the user manual for v5.4.0 and will be available soon, under Enpass User Manual for Traditional Windows.
