The UID can be up to 255 characters long, so you should plan for that worst case in addition to the 32 character subtenant ID and slash. The shared secret is 28 characters long.
Hi  I will be creating an integration with Atmos where my application will be storing the values used for authentication in a database.  So I need to know what the maximum lengths for each of these attributes can be.  From a previous discussion topic, I found that:  The length of the token ID should be 53 chars long, 32 for the subtenant, 1 for the slash, and 20 for the UID  Is this still correct?  Also, what is the maximum length of the shared secret?  Thanks!  - Roger -
