Device registration provides extra security to ensure that even if attackers acquire your account credentials, they can't access your account at HackerOne. Only devices registered to you can log in to your account. Each browser and device will require its own registration. A browser will only have to be registered once.
Registering a Device
To register a device:
Start the login process as normal and you will see a pop-up requiring you to register your device. A message will be sent to your email address with the IP address, user agent, and date. The email must be opened from the same browser that you are registering. This email token will only last 15 minutes and cannot be reused.
Note: If you receive one that is not your device, the attacker will be unable to access your account unless you approve. Changing your password is highly recommended. If you accidentally approve one of these, it will still not allow them to enter as the email must be opened from the same browser you are registering.
Click the Authorize New Device button. This will open a new tab for registering the new device.
Enter a Device Name (optional) - Example: Jane Doe’s MacBook (Safari)
Click Register. A screen will appear saying your device has been registered successfully and an email will be sent to your address confirming the registration.
Click Sign In and sign in as normal.
To manage your registered devices:
Click the dropdown next to your profile icon in the top right corner of your screen.
You will see a tab called Account Security. From here, you can manage two-factor authentication settings and registered devices, and see all past and current sessions.
If you remove a device that’s no longer in use, any active sessions on that device will be ended, and a device-removed email will be sent to your email address. If you try to log in with that device again, you will have to re-register it as you did before.
