When Universal Migrator connects to a cloud system, there are different ways it can do it. The following information summaries the different kinds of connection methods and why/how you would use each one.
Browser Authentication
Browser Authentication use the application's published APIs for communicating with the system.
Bot-Clicker Authentication
Bot-Clicker Authentication simulates an automated web browser that clicks around on the website copies data out.
User Authentication
You provide Universal Migrator a username and password and it will log in to the application.
CSV Authentication
You provide Universal Migrator a CSV with usernames and passwords and it will log in to the application. This is essentially a bulk User Authentication feature.
Access Token Authentication
Some systems, when you authenticate, they provide an access token. This is a really long block of text that will let you log back in without re-entering a username and password. Access tokens are great for re-authenticating to accounts that have two-factor authentication enabled.
Access tokens expire after a certain amount of time (it varies by system.)
Refresh Token Authentication
A refresh token is similar to an access token except they often change each time you use them.
Refresh tokens generally expire after each use and generate a new refresh token.
