About Duo Authentication

Passwords are becoming increasingly easy to compromise. They can often be stolen, guessed, and hacked — you might not even know who else has your password and is accessing your account. Duo two-factor authentication adds a second layer of security to your account to make sure that it stays safe, even if someone else knows your password, by using your phone or other device to verify your identity. You will be alerted right away (on your phone – mobile or landline – or tablet) if someone tries to log in using your password. This prevents anyone but you from accessing your accounts.

If you need any assistance in setting up your Duo Authentication contact Tech Cafe (210) 458-5555.

 You will have three options available to setup your duo

  • "Send me a push" for mobile phones
  • "Call Me" for mobile phones or landlines
  • "Enter a Passcode" for mobile phones or tablets a randomized passcode will appear to be entered

To setup your cell phone or tablet you will need to go to the Apple App Store or Android Google Play Store to search for Duo Mobile and install the app.
