Zoho OneAuth, a free multi-factor authentication app, adds a firm layer of security to your account to protect it from password breaches.Enables single sign-on and works even when your device goes offline. Experience a seamless single sign-on: You need only to sign in to your OneAuth app to access all of the Zoho services on your device. Once you log in to OneAuth, tapping any other Zoho app will give you immediate access—no credentials needed or hurdles to jump. Secondary devices for backup: You can install OneAuth on multiple devices and designate any one of them to be the primary device for multi factor authentication. This can help when you don't have your primary device with you, but you're trying to log in to your account on your laptop or other mobile device. Works even when your device goes offline: Wondering what'll happen if your OneAuth device goes offline and you're trying to log in to your Zoho account on another device or computer? We've got you covered. We detect the scenario automatically and provide you with options to generate offline tokens, so that you can access your account without any trouble. Setup Locations to get freed of notifications: If you're someone who often logs in and out and finds push notifications to be too much, you can simply mark your current location as "safe location." Once marked, notifications will cease whenever you're at the designated location, say your office. Take control of your sessions: With the increase of the multiple device lifestyle, it's essential to know your active web sessions to ensure authorized use of your account. The OneAuth app gives you a list of active Zoho sessions, with details, and if you find any one of them suspicious, you can end it with just a swipe. Restrict access with a single swipe:
