Masterkey.cryptomator plain text file

Hi,

when I add existing vault (created on mobile app) to the desktop app it automatically creates plain text files:

masterkey.cryptomator.D1FB8CD9.bkup
vault.cryptomator.478F5S61.bkup

what is this files for? Is it to recovery access to the vault? Why it’s plain text?

Hi.

Yes, those are backups of the files which are created every time you unlock your vault.
These files are essential to unlock your vault (together with your password). The masterkey file is encrypted, not plain text.

See here for details: Security Architecture — Cryptomator Documentation
Or here: Why is the masterkey stored in the cloud?

Maybe these helps

Those text files just plain text and did created automatically only when I added the existing vault

The content of the masterkey file is encrypted. See my links above.
