You can choose your challenge level, which determines how often you're asked to authenticate when you access a WebAuth-protected Stanford site. You have two choices.
- Open a browser and visit the Stanford Accounts Application
- Click Manage.
- Click the Two-Step Auth tab.
- Click Set level.
- You are presented with two choices:
- The Require two-step authentication once per device every 28 days challenge level is the default when you finish setting up two-step authentication for the first time. At this level, our systems require you to authenticate at least once every 28 days per device per browser (as well as when you log in to a site that requires two-step authentication). You may be challenged more often, depending on the requirements of each site and your browser settings.
- The Always challenge level requires you to authenticate whenever you access a WebAuth-protected Stanford site. This ensures that no one can log into your account without both knowing your password and having your device. This provides the highest level of security and can help foil attempts by others to get into your Stanford account.
- Click the option that you prefer. Your level will be set accordingly and you will return to the Two-Step Authentication settings page.
Reset two-step authentication for all browsers
If your challenge level is set to Require two-step authentication once per device every 28 days, you are presented with an additional button when you return to the Two-Step Auth settings page. The Reset two-step authentication for all browsers button erases record of recently used browsers on computers or mobile devices. You will be prompted to authenticate with two-step the next time you log in, on each device. This can provide an extra measure of security if you are using a public or shared computer.
Make sure you have access to your default two-step authentication device.. Then:
- Click Reset two-step authentication for all browsers.
- On the next page, click Reset two-step authentication for all browsers or click cancel to return to the settings page. Note: this action cannot be undone. However, as you start to log in from your customary locations, they will be remembered for subsequent logins.
