It may be interesting to decode the token in order to learn about its content.
For example, knowing the lifespan of the token or checking the authorized scopes (rights).


The jwt.ms utility allows you to decode a token, just paste the token:

  1. The Decoded token tab displays the summary of the token content.
  2. The Claims tab displays the detail, for example exp indicates the expiration date of the token.

In example below a token (voluntarily altered) that can be copied then pasted in the jwt.ms window below the example token.
