Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Better Auth — Two-Factor Authentication
Adds two-factor authentication via TOTP authenticator apps, email/SMS OTP codes, and backup codes.
## When to Apply
- Adding TOTP (authenticator app) 2FA to Better Auth apps
- Implementing email/SMS OTP verification flows
- Setting up backup code recovery
- Handling 2FA redirects during sign-in
- Configuring trusted device management
## Server Setup
```ts
import { betterAuth } from "better-auth";
import { twoFactor } from "better-auth/plugins";
export const auth = betterAuth({
appName: "My App",
plugins: [
twoFactor({
issuer: "My App",
}),
],
});
```
Run `npx @better-auth/cli migrate` — creates `twoFactorSecret` column on user table.
## Client Setup
```ts
import { createAuthClient } from "better-auth/client";
import { twoFactorClient } from "better-auth/client/plugins";
export const authClient = createAuthClient({
plugins: [
twoFactorClient({
onTwoFactorRedirect() {
window.location.href = "/2fa";
},
}),
],
});
```
## Enabling 2FA for Users
Requires password verification. Returns TOTP URI (for QR code) and backup codes.

How to install
mdr add tekkiiiii/the-agency/better-auth-two-factor@sha256:48a8ba8a4e306e06The line at the top of this page pins the label git:20260508.9e8707b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
