As an admin, when you create a new user, the recipient will only have a fixed amount of time to click the link before it expires and cannot be used.
Administrators can re-send the invitation to the user, by navigating to the Settings/Permissions page and clicking the 'X' icon shown on their profile card:
Please note: The link expiry timeframe is set as part of our adherence to security standards, specifically aligned with the principles outlined in ISO/IEC 27001, the international standard for information security management. Short-lived links are a security measure designed to minimise the risk of unauthorised access. By limiting the validity period, we reduce the potential for misuse if a link is intercepted, accidentally shared, or left unattended. This approach reflects best practices under the standard, such as robust access controls, risk mitigation, and secure management of sensitive data.
