# What happens when my session expires?

When either limit is reached:

1. Your session is ended on the server.
2. You are redirected to the login page.
3. You may see a message such as *“Your session has expired due to inactivity. Please login again.”* or *“Your session has expired. Please login again.”*
4. You sign in again with your username and password (and two-factor authentication, if enabled).

Unsaved work in an open form may be lost if the session ends before you save. Save important changes regularly, especially on long forms.
