"Trust this Browser" Option for Duo

Summary

You can set Duo to remember your authentication for a predetermined period of time. This allows you to authenticate once, and then not have to do so again (on that computer/device) when logging into your account during this time period. Currently, the time period is set to 30 days.

NOTE: You should never select the “Trust This Browser” option on shared or public computers.

Troubleshooting

What if I clicked the “Trust this Browser” button but I am still being asked to authenticate?

This setting must be applied to each browser you use on each computer you use. If you choose this setting but login later with a different browser or computer you will have to set it again for that browser during authentication. If you are certain you chose it to remember you on both the computer and the browser you are using, then it might be a setting on the browser that is not saving your choice.
