I secure who
gets in.Then I ship the app for it.
I'm Hunter Eddington, a System & IAM Engineer. By day I harden identity platforms and access controls. On the side I build iOS apps that bring the same rigor to your pocket.

One-tap setup from apps that integrate with it.
Now
Why it exists
Zero-knowledge by architecture, not by promise.
I spend my days making sure the second factor can't be phished, synced away or leaked. Autheris is that same thinking packaged for everyone else.
Explore Autheris →01
Codes stay in your Keychain
No account, no server, no tracking. Secrets are stored on-device and never phone home.
02
Import in minutes
Move over from Google Authenticator, Aegis, andOTP or 2FAS, or scan a QR code.
03
Clipboard that cleans up
Tap to copy, and the code is cleared from the clipboard after 60 seconds.
04
App Lock
Face ID, Touch ID or passcode, plus blur in the app switcher and during screen recording.
05
Optional E2E iCloud Sync
Keep iPhone, iPad, Mac and Watch in step without anyone else being able to read it.
06
Open source, ad-free
MIT licensed on GitHub. Free on the App Store, with nothing to upsell.
I'm a System Engineer and IAM Engineer. My work centers on designing and hardening infrastructure, identity systems, and access controls so that the right people and systems get the right access, and nothing more.
Most days I'm in Entra ID, Okta, AWS IAM and custom IdP integrations: writing policies, auditing access, and building zero trust frameworks that hold up under pressure. I automate with Terraform, Python and PowerShell because manual processes don't scale and they breed drift.
On Apple platforms I build tools like Autheris, and I write about IAM hardening, authentication patterns and threat intelligence on the blog.
