If you have lost your device, enter your Expo ID and password on a new device, log in, and then go to the Identity Verification page and set up your identity verification method. After that, access the login page again and follow the instructions on the screen to set up your identity verification, then you will be able to log in from the new device. If you have already set up one-time password authentication (by email), you can log in and confirm your identity without having to make any special settings.
