# Two-Factor Authentication

> Enable, use, and manage two-factor authentication for your Ryno account.

Two-factor authentication (2FA) adds an extra layer of protection to your account by requiring a 6-digit code from your authenticator app when you sign in.

## Before 2FA is enabled

When 2FA is disabled, the page shows a warning that your account is at risk and that 2FA is required for some sensitive actions.

## Enable 2FA

<Steps>
  <Step title="Open Settings">
    Go to **Settings** from the left navigation.
  </Step>

  <Step title="Open 2FA Security">
    Under **Privacy & Security**, select **2FA Security**.
  </Step>

  <Step title="Select Enable 2FA Security">
    Use the button on the card to begin setup.
  </Step>

  <Step title="Complete setup with your authenticator app">
    Scan or connect the authenticator app as prompted and save any backup codes provided.
  </Step>

  <Step title="Confirm setup">
    Finish the verification flow so 2FA becomes active on your account.

## What happens after 2FA is enabled

Once enabled:

* Sign-ins require a code from your authenticator app
* You can regenerate backup codes
* You can disable 2FA later if needed

## 2FA during sign-in

After you enter your email address and password, Ryno prompts you to enter the 6-digit code from your authenticator app.

You can also choose **Use a backup code instead** if you do not have access to your authenticator app.

## When 2FA is required

Based on the interface shown, 2FA is required before you can:

* Generate API keys
* Initiate payouts
* Modify payout details

<Info>
  If you lose access to your authenticator app, try a backup code first. If that does not work, contact Ryno Support.
