This article clarifies the behavior when a user attempts to sign up with an existing email address or phone number via Universal Login Passwordless connections.

• Passwordless Connections
• Universal Login

When a database connection is established, an error message is displayed if an attempt is made to sign up with an existing email address. Entering an existing email address and its correct password on the signup screen will not trigger a transition to the login flow.

However, with a Passwordless connection in Universal Login, if the user tries to sign up with a pre-existing email address or phone number, they are logged in directly without seeing an error message such as "This account is already registered."

This is because the signup action is treated as an initial login with a Passwordless connection.
