Profile login hour restrictions
Key Takeaway
Login hours are set on a profile, so every user assigned that profile gets the same allowed days and times for logging in to Salesforce.
Profile login hours let an admin set the days and times when users with a given profile can log in to Salesforce. Controlling who can log in, and when and where they can log in, protects data at the broadest level, the org itself. Object, field, and record access are the other three levels of data access control, and they come into play after that.
Login hours are set on the profile
Every Salesforce user has exactly one profile. The profile defines default settings such as login restrictions and password policies. Login hours are set on the profile, so every user assigned that profile gets the same allowed hours.
For example, imagine call center staff who only need customer data during a nine-to-five shift. An admin can use login hours to block them from logging in on evenings and weekends.
