# Verification link expiration FAQ

### How long is a verification link valid for?
By default, a verification link is valid for **48 hours** from the moment it's created. However, for security reasons, the link may expire sooner if the user begins the verification process but does not complete it (see below).
### A user says their link expired immediately or well before the 48-hour mark. Why?
This usually happens because the link allows for "single use" to protect privacy. Once a user clicks the link and begins interacting with the flow, specifically, once they consent or enter information, the link is considered "consumed".
* **The Safety Feature**: If a user starts the flow, enters sensitive data, and then abandons the session by closing the tab, that link becomes invalid. This prevents a different person from clicking the same link later and seeing the previous user's pre-filled private information.
* **The Fix**: If a user abandons a session, a brand new link must be generated to continue to session.
### Can the user keep the tab open and finish later?
They have a limited window. Once the verification flow starts and the user performs any actions, the user has **1 hour** to complete the process in that specific browser tab. This ensures that a device left unattended does not expose sensitive data to passersby.
