Hi,

I’m looking for a way to identify user performing OTP from a new or unknown device.

Currently, my way of implementation is looking at the auth0 log for type `gd_auth_succeed` where device id is new but somehow when re-OTP from the same browser and device, Auth0 somehow generate new device id.

Backup plan is to look and store the user\_agent value but somehow, it may not be accurate as user may perform OTP from the same browser and OS but on different laptop.

Example of user\_agent value: `Chrome 79.0.3945 / Windows 10.0.0`

Thanks,

Santo

Hi @santo. I’m afraid there’s no current feature, AFAIK, that’ll let you do that.

Thanks for the response @nicolas_sabena.

Sounds like these are my best bet for the time being…
