Analyzing session token generation with Burp Suite - Port Swigger
Summary: PortSwigger describes using Burp Sequencer to collect a large number of session tokens and analyze them for predictability, since predictable tokens can expose sites to session hijacking. The walkthrough uses the deliberately vulnerable demo site ginandjuice.shop with credentials carlos:hunter2, and the Summary tab gives an overall assessment of token randomness.
Bottom line: A predictable session token lets an attacker reach another user's active session, and if that session is authenticated, the attacker can access the user's data and perform operations on their behalf.
