# Fixing Google Authenticator Code Errors

The most common fixes for OTP (One Time Pass) code issues:

1. Look for OTP code in your 2FA app **(not email)**.
2. Sync your 2FA app device and Exchange login device to **the same timezones.**
3. Do you have **multiple 2FA apps** downloaded? Make sure you're checking in the correct one.

**If you cannot resolve OTP issues after verifying the above solutions please reach out to Support via <support@backpack.exchange>**
