@danidee10 We will update the docs accordingly once we approve this PR. Thanks again!

@Annyv2 i also noticed that the JWT's Auth0 generates are an hour ahead of my servers and PyJWT has a library specific check it does to verify that the date and time the token was issued (iat claim) is less than the server's time.

Because of this check i can't validate the JWT in production (Everything work's fine in the Test environment) and it keeps on throwing an error.

InvalidIssuedAtError('Issued At claim (iat) cannot be in the future.')

There are two workarounds for this:

1. Disable the check by passing options={'verify_iat': False} to jwt.decode
2. Bump up the server's time (Not very elegant as other services/apps might malfunction).

So is this something that can be included in the docs for users to watch out for?
Or Maybe i need to configure something else in Auth0?

More context on this issue can be found here jpadilla/pyjwt#190

Thanks for all the great responses so far!
