Requirements
- A Google account
Step-by-Step Verification
- Navigate to the Passport App and connect your wallet.
- Select the Google Stamp.
- Click the verification button to initiate the Google OAuth flow.
- Log in to your Google account and authorize the Passport App.
- The stamp will be added to your Passport.
Deduplication
The Google Stamp uses LIFO (Last In, First Out) deduplication:
- Only one Passport can hold the Google Stamp per Google account.
- If you verify the stamp on a new Passport, it will be automatically removed from any previously linked Passport.
Troubleshooting
- OAuth failed — Try clearing your browser cookies or using an incognito window.
- Wrong account — Make sure you are signing in with the intended Google account. If you have multiple Google accounts, select the correct one during the OAuth flow.
- Stamp removed from old Passport — This is expected behavior due to LIFO deduplication. Each Google account can only be linked to one Passport at a time.
