Memo supports Google sign-in and email OTP login. You can usually use either method with the same email address.

## Email OTP is not arriving

- Check your spam or junk folder.

- Confirm the email address is typed correctly.

- Wait a few minutes before requesting another code.

- If your email is a Google account, try **Continue with Google** instead.

## The OTP code is invalid or expired

- Use the newest code from your inbox.

- Refresh the login page and request a fresh code.

- Enter the code without extra spaces.

## Google login is not working

- Make sure you select the correct Google account.

- Try the email OTP method with the same address.

- Clear cookies for Memo and try again.

- Try a private/incognito window.

## Browser or device issues

- Update your browser.

- Disable extensions that block sign-in popups or cookies.

- Try another browser such as Chrome, Safari, or Firefox.

- If using the mobile app or installed web app, try logging in from a browser to confirm the account works.

## Subscription or billing account mismatch

If you can log in but do not see your expected plan, you may be signed in with a different email from the one used at checkout. Check **Settings → Subscription** and contact support with both possible emails if needed.

## Contact support

If you still cannot log in, contact support and include:

- the email address you are trying to use

- whether you tried Google, OTP, or both

- your browser and device

- screenshots of any error messages
