Expose mfa_token in the Auth0Error class

[DeadHeadRussell]

Describe the problem

The Auth0Error class handles the mfa_required error but does not have a way for the client to access the mfa_token field in the response body.

What was the expected behavior?

Add a way to access the underlying content parameter for the Auth0Error class or another method that allows accessing the mfa_token field.

Reproduction

from auth0.v3.authentication import GetToken

auth0_domain = ' ... '
username = ' ... some user that requires mfa to login ... '
password = ' ... '
client_id = ' ... '
auth0_audience = ' ... '

try:
    resp = GetToken(auth0_domain).login(client_id, None, username, password, None, None, auth0_audience, grant_type='password')
except Auth0Error as e:
    if e.error_code == 'mfa_required':
        e.content['mfa_token'] # This part currently doesn't exist

Hi @DeadHeadRussell - thanks for raising this

Yep - we should add this (similar to auth0/auth0-java#123)

Will add something to the backlog and update this issue with any progress

hey @DeadHeadRussell @adamjmcgrath,

this issue is related with your MFA rule in auth0 setting.

// add privilege scope to AT
  context.accessToken.scope = requestedScopes;

  // enforce 2FA
  context.multifactor = {
      provider: 'any'
  };
