permission set

What is Permission Sets?

Permission set is also very similar to profile. What ever you can manage at profiles (Like Object permissions, Field Permissions, User permissions, Tab settings, App settings, Apex class permission, visualforce permission) the same you can manage here also. But the main difference between these two is that user can have only one profile and can have multiple permission sets at time.

So we can define profiles to grant minimum permissions and settings that every type of user needs, then we can use permission set to grant additional access.

Examples: 

1. We have many user in your organization with some fundamental job functions. We can assign all of then with one profile that grants them all access to do their job. But some set of people are working on special apps or some special functionality, for this type of special users we can create permission sets and can be assigned to them.

2. Some users need some temporary access to specific set of  fields and objects we can create permission set with those object & field access and we can assign that specific users.
