refreshTokenValidity

The refresh token time limit. After this limit expires, your user can't use their refresh token. To specify the time unit for RefreshTokenValidity as seconds , minutes , hours , or days , set a TokenValidityUnits value in your API request. For example, when you set RefreshTokenValidity as 10 and TokenValidityUnits as days , your user can refresh their session and retrieve new access and ID tokens for 10 days. The default time unit for RefreshTokenValidity in an API request is days. You can't set RefreshTokenValidity to 0. If you do, Amazon Cognito overrides the value with the default value of 30 days.
