Switch from Stratum to Tokn
Stratum - formerly Authenticator Pro - and Tokn are close relatives: open source, offline, encrypted. Tokn reads Stratum backup files directly, so the switch is a two-step export and import.
How to switch, step by step
- 1
Export a Stratum backup
In Stratum, open Settings, then Backup, and save an encrypted backup file to your device.
- 2
Install Tokn
Get Tokn from Google Play or F-Droid. There is no account to create - set a vault password or fingerprint unlock and you are ready.
- 3
Import the file in Tokn
In Tokn, open Import, choose Stratum, pick the backup file, and enter its password. All tokens come across in one pass.
- 4
Verify and clean up
Check that a few codes match, create an encrypted Tokn backup, then wipe Stratum and delete the exported file.
