Introducing Two-Factor Authentication` We've rolled out two-factor authentication for Sentry to enhance security. You can use U2F devices, Google Authenticator, or SMS as a second factor for sign-in and sudo prompts. Enrollment is available in account settings, and you'll be prompted for your second factor after passing the password prompt during sign-in. This feature also allows you to confirm sudo prompts with a U2F device and view who has two-factor authentication enabled in the organization list.
