What happens when a user clicks the email verification link in Laravel?

In Laravel's built-in email verification system, what is the expected behavior when a user clicks the verification link sent to their email?

A The user's email_verified_at field is updated, and they are redirected to a verified home page.

B The user is asked to enter their password again before verification completes.

C The verification link expires immediately and shows an error page.

D The user is automatically logged out and redirected to the login page.

💡 Hint

Think about what Laravel does to mark the email as verified and where it sends the user afterward.

When the user clicks the verification link, Laravel updates the email_verified_at timestamp in the database and redirects the user to a page confirming verification or the intended home page.

Why does the email verification link show 'Invalid signature' error?

A user clicks the email verification link but sees an 'Invalid signature' error. Which of the following is the most likely cause?

A The user's email_verified_at field is already set.

B The verification URL was modified or expired before clicking.

C The User model does not implement MustVerifyEmail interface.

💡 Hint

Think about what Laravel checks when validating the verification link.

Laravel signs the verification URL with a temporary signed route. If the URL is changed or expired, the signature becomes invalid.
