This article addresses common questions regarding the conditions and limitations of Okta activation links.

Q: Does the activation token become invalid once the link is accessed?

     Context: Some users receive an activation link is not valid error, suggesting the link may be triggered by security scanners (for example, Outlook Safe Links) before the user clicks it.

A: Yes. Once the URL is accessed, the token is consumed and cannot be reused.

Q: Can this be prevented by requiring the registration process to be completed before the link expires?

A: No. This limitation is a security requirement. If a link becomes invalid, the user must request a new one.

Q: How long does the session last once the link is clicked, and how much time does a user have to complete registration?

A: The session lasts 5 minutes. This duration is fixed and cannot be modified.
