About additional sign up and log in details
In order to keep Twitter safe, we may ask certain users to provide additional information when signing up or logging in.
For example, when signing up for a new account, you may be asked to provide a phone number and/or an email address.
When logging in to an existing account, we may ask you to answer a question about your account that only you know. In some cases, we may also email you a code that you can use to verify your identity and log in to your account.
If you are unable to provide the requested information and need assistance setting up your account, please contact our support team.
