How to Secure OpenAI/ChatGPT with a Passkey

Sign In to ChatGPT Without a Password

Web

From ChatGPT's Security settings, add a passkey, choose a security key instead of your device's built-in biometrics, then connect your Seedkeeper PRO to register it.

Overview​

OpenAI supports passkeys - including hardware security keys - as a secure, convenient way to sign in to your OpenAI account without a password. This guide walks through registering your Seedkeeper PRO as that passkey.

Not available on every account

Passkey availability depends on how your account was created. If your account doesn't have an email address, or is managed by an organization using SSO, the Passkeys option won't appear in Security settings the same way - see the FAQ below.

Why choose the security key option?

The default your browser offers - Face ID, Touch ID, Windows Hello, or a synced credential manager - creates a perfectly valid passkey.

Choosing your Seedkeeper PRO instead changes three things:

  • The key exists in one place only. A synced passkey is copied across every device on your cloud account, and that account is usually protected by a password. A hardware passkey is generated inside a certified secure element and physically cannot leave it.
  • Nobody else is in the chain. No provider account, no cloud, no vendor login standing between you and your own credentials.
  • It travels. The same card or ring works on your phone, your laptop, and a machine that isn't yours - a work computer, a shared workstation - leaving nothing behind.

Step-by-Step Instructions​

Step 1: Sign in to ChatGPT on the web​

Step 2: Go to Settings​

Step 3: Go to Security​

Step 4: Add a passkey​

Under Passkeys, select Add passkey and follow the on-screen instructions.

Step 5: Choose a security key instead of your device​

You'll be offered your device's biometrics or a synced credential manager by default. Look for an option like Use another device or Security key instead, so you can register your Seedkeeper PRO.

Step 6: Connect your Seedkeeper PRO​

Insert your Seedkeeper PRO, or tap it against an NFC reader.

Step 7: Enter your PIN​

Provide your passkey PIN to complete the registration.

Once set up, your Seedkeeper PRO becomes the default way to sign in after you enter your email - no password or separate MFA code needed.

Managing Your Passkeys​

Go to Settings → Security → Passkeys to add another passkey or remove an existing one.

Advanced Account Security

If you turn on Advanced Account Security, OpenAI requires at least two secure sign-in methods, including one that works across devices (like a synced passkey or a security key). See Passkey Backup Strategy for a recommended setup with multiple Seedkeeper PRO devices.

FAQ​

Why don't I see the option to add a passkey?

Passkey availability depends on your account setup - accounts without an email address, or managed by an organization's SSO, won't show this option the same way. See the Overview above.

Does adding a passkey remove my password?

No. If you'd rather sign in with your password, select Try another method during sign-in.

Can I add more than one Seedkeeper PRO as a backup?

Yes - see Passkey Backup Strategy for a recommended setup.

Why register a Seedkeeper PRO instead of my phone's built-in passkey?

Both are phishing-resistant, so this is about what your credentials depend on. A synced passkey depends on a company and an account you hold with them. A hardware passkey depends on an object in your pocket and nothing else. Given that OpenAI protects your conversation history and API access, removing the third party is generally the point.
