Sign in
Prototype sign-in: choose a user. Each user's roles are assigned by a system administrator (Administration → Users & roles)
and can't be chosen here. It's offered only while no single sign-on provider is set up (or in Development) - see
Single sign-on and SCIM.
At an in-person register, staff use the till instead - /till on the register's enrolled machine, signing in with their PIN.
To test segregation of duties, sign out and sign in as a different user.
