From Google Authenticator
Google Authenticator exports as QR codes. Vault2FA reads them directly — dozens of accounts in a minute.
Short version: Export as QR codes, scan them. Two minutes.
Steps
- Start the export
In Google Authenticator tap the menu (≡) → Transfer accounts → Export accounts. Confirm with your device passcode. Select the accounts and tap Next.
- Scan each QR
Google shows one QR per ten accounts. In Vault2FA tap + → Scan QR code and point it at each one. If both are on the same phone, screenshot the QR, then use Choose a screenshot instead in the scanner.
- Review
Vault2FA lists what it found and skips anything already on the phone. Tap Import.
- Turn off Google's cloud sync
If your codes were syncing to your Google account, that copy remains until you disable it: Google Authenticator → account menu → Use without an account. Then delete the app.
Worth knowing
- The export format (
otpauth-migration://) is documented and Vault2FA decodes it itself; nothing leaves the phone. - Steam codes can't live in Google Authenticator anyway, so there's nothing to lose there.
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.
