Major email providers Google, Microsoft and Yahoo now support passkeys. However, banks and brokerages – likely where most of your money is kept – have been slow to adopt passkeys. Here’s a non-comprehensive list of websites that support passkeys: passkeys.directory

How to Set Up a Passkey

  1. Go to the account’s security settings — For example, in your Google Account, look for Security > Passkeys.
  2. Click “Create a passkey” — The website will guide you through setup.
  3. Choose where to store the passkey — Your device will usually suggest saving it to your platform’s password manager (Google Password Manager, Apple’s iCloud Passwords & Keychain or Windows Hello).
  4. Verify yourself — Confirm with Face ID, Touch ID, fingerprint, or PIN to finish creating the passkey.

💡 Tip: You don’t have to create the passkey on just one device—you can (and should) create a passkey for the same account on multiple devices!
