Auto-Login enables your users to access and download new assets without the need to log-in manually.
It is proven to lower the threshold for user-engagement and is also useful if your are dealing with a lot of customer-support-issues that revolve around authentication.
Auto-Login can be enabled platform-wide for all users in "Settings" -> "Security" or individually on a user-basis in the user-settings. Please be aware that the platform-wide setting takes precedence over the user-setting when activated. (no opt-out on a user-basis possible).
Before enabling that feature please keep in mind that everyone receiving the "New file available"-emails will be able to log-in as the respective user by simply following the download-link in the email.
Auto-Login is only valid for the first three uses of the provided link. Every subsequent use needs to be authenticated.
