otp-migrate.sccl.cc

Client-side Google Authenticator OTP migration decoder.

What it does

Google Authenticator exports accounts as a single QR using the otpauth-migration:// URI scheme - a google-specific protobuf format. Other apps (Bitwarden, Authy, Aegis) don't understand it.

This tool decodes that format and gives you standard otpauth:// keys that work everywhere.

How to use

1. Open Google Authenticator -> Settings -> Export accounts
2. Select accounts -> you'll get a big QR code
3. Go to otp-migrate.sccl.cc
4. Drop/upload the QR image or paste the otpauth-migration:// URL
5. Get individual otpauth:// URIs and QR codes for each account
6. Import into Bitwarden, Authy, or any TOTP-compatible app
