 ### Session idle timeout
 
-Controls how long a member can stay inactive before being signed out. The value must be a whole number of minutes, 15 or higher, and the Anthropic default is 1440 minutes (24 hours). A lower value applies at the next sign-in; a higher value applies on the next request. This is a restriction, so each level can shorten the timeout but not lengthen it past what the level above allows, and the value that takes effect is always the shortest one in the chain.
+Controls how long a member can stay inactive before being signed out. The value must be a whole number of minutes from 15 to 5,760 (96 hours), and the default is 1,440 minutes (24 hours) until your tenant sets a value. This is a restriction, so organizations and groups can only set a shorter timeout than the tenant.
 
 ### Maximum session length
 

 
 ## How long sessions last
 
-Sessions expire after a period of inactivity, and using a session extends it. Once you have been inactive for longer than the idle timeout, that browser tab or desktop application prompts you to sign in again the next time it tries to do anything. The idle timeout is set by your agency or organization; unless they have chosen a shorter value, it is 24 hours.
+Sessions expire after a period of inactivity, and using a session extends it. Once you have been inactive for longer than the idle timeout, that browser tab or desktop application prompts you to sign in again the next time it tries to do anything. Your agency or organization sets the idle timeout, which is 24 hours unless they have changed it.
 
 Your agency or organization can set a maximum session length in addition to the idle timeout. When a session reaches that length, it expires even if you have been using it the whole time, and the browser tab or desktop application prompts you to sign in again. Sessions that expire either way drop off this list automatically.
