Smile Auth
Download

Smile Auth on all your devices

Everything syncs through your Smile account. Step-by-step guides for each device are in Smile Docs.

Windows

Windows 10 and 11, 64-bit

Smile Auth, passwords, Hosting, SmileMail and VPS in one app. Locks with Windows and updates itself (signed).

Download for Windows
How to install
  1. Run the installer - no admin rights needed.
  2. If Windows says "Windows protected your PC" (the app is new): More info → Run anyway.
  3. Sign in with your Smile account.

Android

Android 9 or newer

Fills logins, 2FA codes and passkeys in other apps and browsers. Fingerprint unlock. Updates itself (signed).

Download for Android
How to install
  1. Open this page on your phone and tap Download for Android.
  2. Open the file. Allow installing apps from your browser once, then tap Install.
  3. Sign in. To fill logins and passkeys in other apps, turn them on in Smile's Settings.

iPhone & iPad

iOS 16 or newer

The same app as Android. Not in the App Store - install it on your iPhone with KSign (no computer), and get new versions there in a tap.

Add Smile to KSign Download the .ipa

How to install with KSign (on your iPhone)
  1. Have KSign on your iPhone with a signing certificate imported - your own Apple Developer certificate, or one from someone you trust.
  2. Tap Add Smile to KSign above. (Or in KSign: Sources → + and paste https://auth.smilecorp.co.uk/downloads/ios/source.json.)
  3. In KSign open Smile → Get, then Sign and Install. Open Smile and sign in.
  4. New versions show up in Smile's source in KSign - and Smile's Settings → About → Get it sends them straight to KSign. Sign and install; your vault is kept.
  5. To fill passwords in other apps: Settings → General → AutoFill & Passwords → AutoFill from → Smile (only if the signing certificate allows AutoFill).
Other ways: with a computer (Sideloadly) or another signer
  1. The .ipa button above is the app file itself - for any signer (KSign, Feather, ESign, Scarlet, Sideloadly, AltStore).
  2. Sideloadly (Windows PC or Mac, sideloadly.io): on Windows also install iTunes and iCloud from apple.com. Plug in your iPhone, drag the .ipa in, type your Apple ID and click Start.
  3. Then on the iPhone: Settings → Privacy & Security → Developer Mode on (it restarts), and Settings → General → VPN & Device Management → your Apple ID → Trust.
  4. With a free Apple ID the app stops opening after 7 days - click Start in Sideloadly again (your vault is kept).

Linux & ChromeOS Beta

64-bit PCs and Chromebooks

The Windows app as an AppImage - nothing to install. On Ubuntu, Debian or Mint you can install the .deb instead. Both update themselves (signed).

Download for Linux (.AppImage) .deb for Ubuntu / Debian
How to install
  1. .deb: double-click it to open it in Software, or run sudo apt install ./smile_*_amd64.deb. Smile shows up in your apps.
  2. AppImage: right-click it → Properties → Allow executing as a program (or chmod +x Smile-*.AppImage), then open it.
  3. To stay signed in you need a keyring (GNOME Keyring or KWallet). Without one Smile keeps nothing on disk.
  4. Ubuntu 24.04+: if it doesn't open, let Smile use its security sandbox: 
    printf 'abi <abi/4.0>,
include <tunables/global>
profile smile /tmp/.mount_Smile*/usr/lib/smile/smile flags=(unconfined) {
  userns,
}
' | sudo tee /etc/apparmor.d/smile-app
sudo apparmor_parser -r /etc/apparmor.d/smile-app

Chrome extension

Chrome, Edge, Brave, Opera

A Smile icon in login boxes with a "Log in as..." list, 2FA codes, passkeys and QR scanning. From the Chrome Web Store - it updates itself.

Add to Chrome Download the .zip
How to install
  1. Press Add to Chrome above, then Add to Chrome on the store page.
  2. Edge: on the store page choose Allow extensions from other stores first. Brave works as it is. Opera: add the Install Chrome Extensions add-on first.
  3. Pin Smile Auth from the puzzle-piece menu, click it and sign in.
Install it by hand (without the store)
  1. Download the extension (.zip) and unzip it into a folder you'll keep.
  2. Open chrome://extensions (or edge://extensions) and turn on Developer mode.
  3. Load unpacked → pick the folder. A copy installed this way doesn't update itself.
