How to confirm an email address

Check the address when it is entered, so you do not send confirmations to addresses that bounce.

Use a single-use token that expires, for example after a day, and say plainly what they are confirming.

Store the time and the token. Only mark the address confirmed after the click, and give people an easy way to resend.

A click shows a person controls the inbox now. Some security scanners open links automatically, so require a button press on the landing page if that matters to you.
