Cisco Duo: Duo Push

If you choose to authenticate with Duo Push, you'll get a login request sent to your phone — just press Approve to authenticate.

If you get a login request that you weren't expecting, press Deny to reject the request. You’ll be asked if this was a suspicious login. If you aren't trying to log into an application or service protected by Duo and don't recognise the request, tap Yes to notify Lineal. If you made a mistake but the login isn't suspicious, tap No to deny the request without reporting it.
