How to Enable Passkeys on Outlook

Sign In to Outlook Without a Password

Mobile and Web

From your Microsoft account's Advanced Security Options, add a new way to sign in, choose Security key, then register your Seedkeeper PRO as your passkey.

Overview​

Microsoft accounts (used across Outlook, Microsoft 365, and other Microsoft services) support passkeys as a password replacement. This guide walks through registering your Seedkeeper PRO as that passkey. Here's what the full flow looks like:

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.

Your Microsoft account is now secured with a passkey stored on your Seedkeeper PRO.

You can also give it a more familiar name by clicking Rename - handy if you use more than one Seedkeeper PRO, so you can tell them apart at a glance (for example, "Seedkeeper PRO - Main", "Ring Backup", "Card Backup").
See Passkey Backup Strategy if you're setting up more than one device.

Deleting a Passkey​

To remove or revoke a passkey, click Remove.

FAQ​

Do I need a PIN before I start?

No - you'll set one up during this process if you don't already have one. See Setting Up Your Passkey PIN for details on that PIN.

Does this remove my Microsoft account password?

No. Adding a passkey doesn't remove or change any existing sign-in or recovery methods on your account. If you'd like to remove it entirely afterward, see How to Replace Passwords with Passkeys on Outlook.

How do I remove a passkey later?
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 Outlook protects your mailbox, which is the reset path for nearly everything else, removing the third party is generally the point. See Are Passkeys Safer?.
