Email OTP or magic link not received
If you or your users do not receive a one-time password (OTP) or magic link email during email passwordless sign-in, an accidental unsubscribe from MetaMask Embedded Wallets (formerly Web3Auth) transactional email may be the cause.
Problem
During email passwordless sign-in, the expected OTP or magic link email never arrives. The sign-in flow may appear to stop responding or time out while waiting for the code.
This often happens after someone clicks Unsubscribe on a previous OTP email from MetaMask Embedded Wallets or Web3Auth. Once unsubscribed, future OTP and magic link messages are blocked for that address.
Solution
Submit the MetaMask Embedded Wallets Email OTP resubscribe request with the following details:
- Full name
- Email address (the same address used for email passwordless sign-in)
- Confirmation that this is the email used to sign in to MetaMask Embedded Wallets or an application that uses it
After you submit the form, Embedded Wallets resubscribes the address automatically. Allow a few minutes for the change to take effect, then try signing in again.
Share the resubscribe form link with end users who report missing OTP emails. No dashboard or API action is required on your side.
Other checks
If emails still do not arrive after resubscribing, verify the following:
- The email address entered at sign-in matches the address submitted on the resubscribe form.
- The message is not in spam, junk, or promotions folders.
- Corporate or school email filters are not blocking messages from the Embedded Wallets mail sender.
- Email passwordless is enabled for your project in the developer dashboard.
For custom email connections, confirm that your own email provider is delivering messages and that the recipient has not unsubscribed from your sender domain.
