Do you support DUO or Yubikey?


We use DUO for our 2-factor authentication with our primary authentication source linked to an on premise DC and not Azure AD, therefore app passwords are not applicable in our configuration.  Will this cause an issue with logins?

  • We do not support this configuration, we rely on Azure to handle the Oauth response. If the accounts are on-prem then we only support basic auth.
  • I do not believe DUO adds to 2fa to EAS / EWS 
  • If it does can you disable it for EWS.
  • Try Duo's "append mode" for authentication with Nylas: We don't have confirmation at this time as to whether this will work, so if you choose to give it a try, please report back!
