When a user registers or changes their email address in their account, the plugin sends an email with a confirmation link to the specified email address. This verifies the email address.
After activation, the plugin creates a settings page: "Settings" - "Email Verification Before Registration."
On this page, you can select a timeout (the time after which the next email will be sent for the current email address).
The email address is verified for the user's session for 5 days, after which the email must be verified again.
