What's New in Authenticator App

4.4.3

October 22, 2026

Zoho OneAuth for iOS 27 is here. OneAuth, unfolded: Built to adapt to iPhone Duo's wide display, OneAuth resizes fluidly — in landscape or during iPhone mirroring on iPad and Mac — so your codes stay open side-by-side while you work in other apps. Ask the OneAuth assistant to perform quick actions: OneAuth Assistant can take action directly from the conversation, from setting up MFA to finding recovery options. It also answers your "how-to" questions and explains security alerts. Visual summary for account activity: Have a look at your missed notifications, categorized as a pie chart, with critical alerts highlighted. Spot anything you missed at a glance. Find 2FA codes from Spotlight Search: Grab the exact 2FA code you need straight from your iPhone's Spotlight Search, without scrolling past other codes set up with OneAuth. Extra-large Home Screen widget: The new 2FA Focus Widget shows more codes at a glance. You can also scan a QR code directly from the widget to sign in to your Zoho account or add a 2FA account to OneAuth.

Annoying

Useless and dangerous

Useless because, even when logged in, it does not synchronize TOTP across devices. Dangerous because it will turn on multi-factor authorization even when you haven’t approved it, thereby locking you out of your own account. There are plenty of good TOTP authenticators. I like Zoho mail but THIS is a hot mess. Do not use it.

Very slick and effective

I've got a few of the usual authenticator apps, but I have to say this one is one of my favourites. It's pretty slick and easy to use. It just feels like it doesn't take up a lot of time compared to others. It's probably only seconds at a time, but it all counts, so I've started using this for more than the initial Zoho suite of products.

Fast and easy and steady

Works flawlessly, very fast and easy. Much easier than other applications I have to go to approvals on other applications currently.

A while back I had a problem scanning with my iPhone, but no issues now. 100% recommend.
