What Are Passkeys, and Should Your Business Use Them?
Article Summary: A passkey lets you sign in to an app or website with the same fingerprint, face, or PIN you use to unlock your phone or laptop. There’s no password to type. Passkeys use a security standard called FIDO, which resists phishing because each passkey only works on the real site. Most major platforms and a growing list of business tools support them, and Microsoft 365 includes them at no extra cost. For most companies, passkeys for business are worth rolling out now, starting with the most sensitive accounts.
Passwords are the weak point in most businesses. People reuse them across accounts, write them on sticky notes, and type them into convincing fake login pages without realizing it.
Passkeys were built to replace passwords, and they fix the parts that cause the most trouble. You sign in with the same fingerprint, face scan, or PIN you already use to unlock your phone or laptop. Since there’s no password, there’s nothing for an attacker to steal, guess, or trick out of you.
At Pacific Edge Technology, we help businesses across Richland, Kennewick, and Pasco strengthen their logins. This post explains what passkeys are and why they’re so much harder to attack than passwords. It also covers how to roll out passkeys for business without locking anyone out.
What is a passkey?
A passkey replaces your password with your device’s built-in security. Instead of typing a password, you prove it’s you the same way you unlock your phone: a fingerprint, a face scan, or a PIN.
When you set up a passkey for a website, your device creates two matching keys. The private key stays locked on your device and never leaves it. The website stores the public key.
When you sign in, the site sends a challenge that only your private key can answer. Your device answers it once you confirm with your fingerprint or PIN, and you’re in. The website never sees a password, because there isn’t one.
This approach comes from a standard called FIDO. Apple, Google, and Microsoft all build on it.
Why passkeys are harder to attack than passwords
With a password, you share a secret with the website every time you log in. That shared secret is exactly what attackers go after. A passkey has no shared secret, and that one difference fixes the biggest problems with passwords.
- They resist phishing. A passkey only works on the real website it was created for. If you land on a convincing fake, the passkey simply won’t work, so there’s nothing to hand over. That matters, because phishing is one of the most common ways attackers break in.
- A data breach exposes no passwords. The website only keeps your public key, which is useless on its own. If hackers break into that company, they find no password list to try on your other accounts.
- There’s nothing to reuse or forget. Your device creates a unique passkey for each site automatically. Reused and weak passwords stop being a problem.
By comparison, attackers can still trick people out of older methods like text message codes and app approval prompts.
Where you can use passkeys today
Support has spread quickly. You can already use passkeys with Microsoft, Google, and Apple accounts. A growing list of banks, password managers, and business tools support them too. Apple, Google, and Microsoft have built passkeys into their phones, laptops, and browsers, so the device in your pocket can already store and use them.
Synced vs. device-bound passkeys
There are two types worth knowing.
A synced passkey backs up to your Apple, Google, or Microsoft account. It works across all your devices, so losing one phone doesn’t lock you out.
A device-bound passkey stays on a single device, such as a physical security key you plug in. It’s the most locked-down option and a common choice for sensitive accounts.
Should you use passkeys for business?
For most businesses, yes, and you can start small. You don’t need to switch everything overnight or drop passwords on day one.
If you use Microsoft 365, passkeys are already available through Microsoft Entra. Staff can sign in with a passkey stored in the Microsoft Authenticator app, on a security key, or on their own device. Google Workspace supports passkeys as well.
Passkeys are also faster. According to Microsoft, signing in with a synced passkey takes about 3 seconds. A password plus a traditional MFA code takes roughly 69 seconds. Across a whole team, that time adds up.
How to start rolling out passkeys
- Turn on passkeys for your most sensitive accounts first. That means administrators, finance staff, and anyone who can move money or change systems.
- Invite everyone else to add a passkey as a faster, safer way to sign in. At first, they can keep their normal login alongside it.
- Make sure each person has a backup, like a second device or a security key, so a lost phone doesn’t lock anyone out.
Your IT provider can turn this on and manage the rollout so nobody gets locked out along the way.
What to watch out for
Passkeys aren’t magic. Plan ahead for a few things.
- Account recovery. Someone who loses the only device holding their passkey, with no backup, can get locked out. A synced passkey or a second registered device solves this, but you need to set it up in advance.
- Not everything supports them yet. Support is growing fast, but some older systems and smaller vendors still rely on passwords. Expect to run both side by side for a while.
- Shared devices and logins. Passkeys belong to one person and their device. Any shared computers or shared accounts need their own plan.

Passkeys for Business FAQs
What is a passkey in simple terms?
It’s a way to log in with your fingerprint, face, or PIN instead of a password. Your device proves your identity to the website, and nobody ever types or stores a password.
Are passkeys safer than passwords?
Yes. They resist phishing, a data breach exposes no passwords, and there’s nothing to reuse or forget. Security agencies like CISA recommend FIDO-based logins, which include passkeys, as the strongest widely available option.
What happens if I lose the device with my passkey?
A synced passkey backs up to your Apple, Google, or Microsoft account, so it’s still available on your other devices. If you lose a device-bound passkey with no backup, you’ll need a recovery method to get back in. That’s why setting up a second passkey or device ahead of time matters.
Does Microsoft 365 support passkeys for business accounts?
Yes. Passkeys come with Microsoft Entra at no extra cost, including the free tier. Staff can use a passkey in the Microsoft Authenticator app, on a security key, or on their own device.
Do passkeys replace multi-factor authentication?
A passkey can count as multi-factor authentication on its own. Unlocking it requires your device (something you have) plus your fingerprint, face, or PIN (something you are or know). That covers two factors in one step and can replace the old password-plus-text-code routine.
