From Bitwarden or Bitwarden Authenticator
Both Bitwarden apps export the same JSON shape. Vault2FA picks out every item that has a TOTP.
Short version: Export unencrypted .json, open it.
Steps
- Export
Bitwarden Authenticator → Settings → Export → .json. Or from the password manager: Settings → Vault → Export vault → .json (not .json (Password protected), and not Encrypted).
- Import
Vault2FA → + → Import from another app → Choose export file. Items without a TOTP are ignored; names, usernames, notes and favourites come across.
- Delete the file
A full vault export contains your passwords too. Delete it the moment the import is done.
Worth knowing
- If you keep using Bitwarden for passwords, you can leave the TOTP seeds out of it entirely — that's the whole point of a separate authenticator.
Afterwards
Make an encrypted backup (Settings → Backup) before you delete the old app, and check the support page if a code is rejected — it is nearly always the phone's clock.
Stuck? support@vault2fa.app. Never send a secret or a backup file by email.
