 ### Email link
 
-When the **Email verification link** option is selected as an authentication strategy, users receive an email with a link to complete the sign-in process. Email links can be used to sign up new users, sign in existing ones, or allow existing users to verify newly entered email addresses to their profile. Email links work on any device. There's no constraint on where the link can be opened. For example, a user might try to sign in from their desktop browser, but open the link from their mobile phone.

+By default, email links can be opened on any device. There's no restriction on where the link can be accessed. For example, a user could try to sign in from their desktop browser but open the link from their mobile phone. In this case, _the user's sign in would be completed on the desktop browser where the process was initiated, not the mobile phone where the link was verified_. As a result, the user would be signed in on their desktop, not their phone.
