From Raivo, andOTP, FreeOTP+ or LastPass Authenticator
All four export JSON that Vault2FA recognises without being told which app it came from.
Short version: Export JSON, open it.
Steps
- Raivo
Settings → Export OTPs → the archive is a password-protected ZIP. Unzip it on a computer; inside is a JSON file. Open that in Vault2FA.
- andOTP
Settings → Backup → Plain-text backup. Open the JSON in Vault2FA.
- FreeOTP+
Settings → Export → JSON. Secrets are stored as byte arrays; Vault2FA converts them.
- LastPass Authenticator
Settings → Export accounts to file. Open the JSON in Vault2FA.
- Anything else
If an app exports JSON or text containing
otpauth://links, Vault2FA will find them regardless of the surrounding structure. Try it.
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.
