What is the maximum length of the OAuth token given by Azure active directory in bytes

Question

I am having a scenario where I have to store OAuth token in a secured store where maximum length allowed is 255 characters.So, I want to know the maximum length of OAuth token delivered by Azure. Is it less then 255?

Answer 1

OAuth tokens returned by Azure AD are essentially base64 encoded JWT tokens and currently there's no maximum length defined (Ref: What is the maximum size of JWT token?).

Having said that, in my experience they are definitely more than 255 characters. See one below for example:
