On your wrist
Two-factor codes without reaching for your phone
Signing in on a laptop, phone in the other room? Raise your wrist, read the code, type it in.
How it works
Built to be quick on the watch and safe off it
Works without your iPhone
Codes are generated on the watch itself from its cached list, so they keep counting down with your iPhone out of reach or switched off.
Read-only by design
There is no editing, copying or settings on the watch. Your iPhone stays the single place your codes are changed, and the watch follows within seconds.
Kept in the watch’s own Keychain
The watch stores its copy with the same this-device-only Keychain protection as the iPhone. Nothing is sent to it until you install the watch app.

FAQ
Apple Watch authenticator questions
Is there a 2FA authenticator app for Apple Watch?
Yes. Autheris has an Apple Watch app that shows your two-factor codes one at a time, each with a live countdown ring. It comes free with the Autheris iPhone app.
Does the Apple Watch authenticator work without my iPhone nearby?
Yes. Codes are generated on the watch from the list your iPhone last sent, so they keep working with your iPhone in another room or switched off.
Can I add or delete 2FA accounts on the watch?
No, and that is deliberate. The watch app is read-only so your iPhone stays the one place your codes are edited. Add or remove an account on the iPhone and the watch follows within seconds.
Which Apple Watch models are supported?
Any Apple Watch running watchOS 26.0 or later, paired with an iPhone running iOS 26.0 or later with Autheris installed.
Are my secrets safe on the watch?
The watch keeps its copy of your accounts in its own Keychain, readable only while the watch is unlocked and never synced elsewhere. Nothing is sent to the watch at all until you install the watch app.
Put your second factor on your wrist
Free on the App Store. Install on iPhone, add the watch app, and your codes are a glance away.
