Common TOTP Errors
Invalid TOTP codes are often caused by time drift, a copied secret with mistakes, or using the wrong account entry.
Why TOTP codes fail
TOTP relies on the secret key and current time being aligned. If either is off, the generated code may be rejected even when it looks correct.
Formatting issues during setup can also break code generation.
Troubleshooting steps
Start by checking your device time, then verify the Base32 secret and account entry. If you migrated devices recently, confirm that the imported secret matches the original.
Many invalid code problems are solved by correcting time sync or re-enrolling 2FA.
- Enable automatic date and time on the device
- Verify the Base32 secret was copied correctly
- Check that you are using the right account
- Re-enroll 2FA if the secret may be corrupted
