How to Use Google Authenticator with Swift2FA During Migration or Recovery
A short workflow note on using the same secret in Google Authenticator and Swift2FA to validate imports and restore access.
Support Note
This page stays available for users but is currently excluded from search indexing while we expand it into a more comprehensive resource.
Quick Summary
- Both tools generate the same code only when the secret and TOTP settings match.
- The safest time to verify a migration is before you lose access to the original authenticator.
- This support note is excluded from indexing while a larger migration guide is prepared.
Key Takeaways
- Preserve the entire QR payload, not just the secret.
- Compare outputs inside the same time window.
- Treat this as a validation workflow.
Start with the same secret and settings
Matching output depends on the same secret, digits, period, and algorithm. If one value changes during import, the generated code can differ.
That is why QR-based imports are usually safer than manual re-entry when the original setup material is still available.
Use it as a verification step
Generate a fresh code on both sides during the same window and compare them before depending on the new workflow.
If the codes do not match, inspect the secret, the QR payload, and the system clock before resetting anything.
FAQ
Will Swift2FA always match Google Authenticator?
Yes, if both sides are using the same secret, the same TOTP settings, and reasonably aligned clocks.
Why are my codes different?
The most common reasons are a mismatched secret, lost QR settings, or device clock drift.
