Connect Gmail without sharing your main password.

1. Try “Sign in with Google” first

Choose the Gmail or Google sign-in option inside your mail app. Review the permissions carefully, then approve only if the app’s privacy policy matches what you expect. For Suzume, Gmail access is used to read, search, organize, and send mail directly between your iPhone or Mac and Google.

2. Use an App Password when OAuth is unavailable

Google App Passwords are separate 16-character codes for apps that use IMAP and SMTP. Your Google account must have two-step verification enabled. Create one at myaccount.google.com/apppasswords ↗, then enter the code into the mail app. Spaces are usually ignored, but entering the 16 characters without spaces is safest.

• Use your full Gmail address as the username.
• Use the App Password, not your normal Google password.
• Keep IMAP on and use TLS.
• Revoke the App Password in Google if you stop using the app.

3. Check the connection before blaming the inbox

A successful sign-in should be followed by folder discovery and an inbox refresh. Give the first sync a moment on a large account. If messages appear but bodies are empty, refresh the folder and check that the app has downloaded the message content rather than only headers.

4. Keep the privacy boundary clear

Your Google account and mail provider still control your mail. A privacy-first app should store credentials in the Apple Keychain, avoid a mail-sync server, and explain whether AI runs locally. Suzume’s mail cache and Gmail credentials stay on your device; your mail travels directly to Google over encrypted IMAP/SMTP.
