docs: refresh the two-factor authentication pages (#26234)

The 2FA section page mixed concepts with enable and disable steps, and
the same recovery-code and sign-in details appeared on more than one
page. This splits procedures onto a manage page, keeps the overview to
how 2FA works and when Docker asks for the code, and leaves the recover
page for the recovery-code and Support steps.

-Two-factor authentication (2FA) adds a security layer to your Docker account by
-requiring a unique security code in addition to your password when signing in.
-This prevents unauthorized access even if your password is compromised.
+Two-factor authentication (2FA) adds a code from an authenticator app to
+your password when you sign in to your Docker account. Someone who knows
+your password still needs the code from your device to sign in.
 
-When you turn on two-factor authentication, Docker provides a unique recovery
-code specific to your account. Store this code securely as it lets you recover
-your account if you lose access to your authenticator app.
-
-## Key benefits
-
-Two-factor authentication improves your account security:
-
-- Protection against password breaches: Even if your password is stolen or
-  leaked, attackers can't access your account without your second factor.
-- Secure CLI access: Required for Docker CLI authentication when 2FA is turned
-  on, ensuring automated tools use personal access tokens instead of passwords.
-- Compliance requirements: Many organizations require 2FA for accessing
-  development and production resources.
-- Peace of mind: Know that your Docker repositories, images, and account
-  settings are protected by industry-standard security practices.
+> [!TIP]
+>
+> Organization and company settings do not include 2FA. To control how
+> members sign in across an organization, use
+> [single sign-on](/manuals/security/authentication/single-sign-on/_index.md).
 
-## Prerequisites
+## How two-factor authentication works
 
-Before turning on two-factor authentication, you need:
+When you turn on 2FA, you pair a time-based one-time password (TOTP)
+authenticator app with your account by scanning a QR code or entering a
+text code. Any authenticator app that supports TOTP works. Docker keeps
+one authenticator per account.
 
-- A smartphone or device with a time-based one-time password (TOTP)
-  authenticator app installed
-- Access to your Docker account password
+After repeated wrong codes, Docker returns `Too many failed login
+attempts` and blocks further attempts for a short time.
 
-## Enable two-factor authentication
+## When Docker asks for the code
 
-To turn on 2FA for your Docker account:
+| Sign-in | What Docker asks for |
+| --- | --- |
+| Browser sign-in to Docker Home or Docker Hub | Your password, then the code from your authenticator app |
+| `docker login` with no username | The same browser sign-in, if the browser is not already signed in |
+| `docker login -u`, scripts, and CI | A [personal access token](/manuals/security/access-tokens/personal-access-tokens.md) in the password prompt. Password sign-in from the CLI is not supported when 2FA is on |
 
-1. Sign in to your [Docker account](https://app.docker.com/login).
-1. Select your avatar and then from the drop-down menu, select **Account
-   settings**.
-1. Select **2FA**.
-1. Enter your account password, then select **Confirm**.
-1. Save your recovery code and store it somewhere safe. You can use your
-   recovery code to recover your account in the event you lose access to your
-   authenticator app.
-1. Use a TOTP mobile app to scan the QR code or enter the text code.
-1. Once you've linked your authenticator app, enter the six-digit code in the
-   text field.
-1. Select **Enable 2FA**.
+## Recovery code
 
-Two-factor authentication is now active on your account. You'll need to enter a
-security code from your authenticator app each time you sign in.
+Docker gives you one recovery code when you turn on 2FA. The code signs
+you in if you lose your authenticator app, so copy, download, or print it
+and store it somewhere safe.
 
-## Disable two-factor authentication
+Docker emails the verified address on your account when you turn 2FA on
+or off, when a recovery code is generated, and when a recovery code is
+used to sign in. The email does not contain the code.
 
-> [!WARNING]
->
-> Disabling two-factor authentication results in decreased security for your
-> Docker account.

+Turn two-factor authentication (2FA) on or off for your Docker account

+code, and what the recovery code does, see
+[Two-factor authentication][overview].
+
+## Prerequisites
+
+Before you turn on 2FA, you need:
+
+- A time-based one-time password (TOTP) authenticator app on your phone or
+  another device
+- Your Docker account password
+- A verified email address on your account
+
+## Enable two-factor authentication
+
+To turn on 2FA for your Docker account:
+
+1. Sign in to your [Docker account](https://app.docker.com/login).
+1. Select your avatar in the top-right corner, then select **Account
+   settings**.
+1. Select **2FA**.
+1. Enter your account password, then select **Confirm**.
+1. Save your recovery code. Select **Copy**, or open the menu next to
+   **Copy** and select **Download** or **Print**.
+1. Open your authenticator app. Scan the code on the **QR Code** tab, or
+   enter the code from the **Text Code** tab.
+1. Enter the six-digit code from your authenticator app in
+   **Authentication code**.
+1. Select **Enable 2FA**.
+
+Two-factor authentication is on. When you sign in with your password,
+Docker asks for a code from your authenticator app. Docker also emails
+you a reminder to save your recovery code.
+
+## Disable two-factor authentication
+
+> [!WARNING]
+>
+> Turning off 2FA leaves your account protected by your password alone.
+
+1. Sign in to your [Docker account](https://app.docker.com/login).
+1. Select your avatar in the top-right corner, then select **Account
+   settings**.
+1. Select **2FA**.
+1. Enter your password, then select **Confirm**.
+1. Select **Disable 2FA**.
+
+Two-factor authentication is off. Docker emails you to confirm the
+change.
+
+## Move 2FA to a new device
+
