A WhatsApp passkey lets you verify your account with your fingerprint, face or phone screen lock instead of waiting for an SMS code. To create one, go to Settings, then Account, then Passkeys, and tap Create passkey. On Android you'll need Android 9 or later with a password manager set up.
SMS codes are the weak spot in most account security. They can be delayed, intercepted or phished out of you with a convincing message. A passkey replaces the code with something only you have: your phone plus your face, fingerprint or screen lock. WhatsApp added passkeys to make getting back into your account both faster and safer, and setting one up takes about a minute. Here's how to do it, what your phone needs first, and what to check when the option won't appear, which is where most people get stuck.
What a WhatsApp passkey does
When you set up a passkey, WhatsApp links your account to your device's own security, such as your fingerprint, face or screen lock. The next time WhatsApp needs to check it's you, for example when you register your number or restore your account, you can use the passkey instead of an SMS code. WhatsApp says your biometric data never leaves your device, so it isn't sent to WhatsApp at all.
How to create a passkey on WhatsApp
- Open WhatsApp and go to Settings.
- Tap Account, then Passkeys.
- Tap Create passkey, then Continue.
- Confirm with your fingerprint, face or screen lock when your phone asks.
What you need before it works
This is why the option sometimes fails. On Android, WhatsApp lists three requirements:
| Requirement | How to check |
|---|---|
| Android 9 or later | Settings, About phone, Android version |
| A password manager linked to your phone | For example Google Password Manager or Samsung Password Manager |
| A lock screen set up | A PIN, pattern, password, fingerprint or face recognition |
WhatsApp suggests checking the password manager is switched on under your phone's Settings, then Passwords, then Passkeys & accounts. The exact menu name can vary by phone maker. On iPhone, the same idea applies: your phone needs a passcode and Face ID or Touch ID set up before WhatsApp can lean on them.
Passkey vs SMS code vs two-step verification
| Method | How you prove it's you | Main weakness |
|---|---|---|
| SMS code | A 6-digit code texted to your number | Can be phished, delayed or intercepted |
| Passkey | Your device plus fingerprint, face or screen lock | Tied to a device you need to keep secure |
| Two-step verification | A password on top of the code | You have to remember it |
A passkey doesn't replace two-step verification. WhatsApp says a passkey lets you log in faster when two-step verification is turned on, so the two work together. Think of the passkey as the quick way in and the password as the backstop that stops anyone else registering your number.
Changing phones with a passkey
If you reinstall WhatsApp and you've created a passkey before, WhatsApp may ask if you want to use it when you register. Passkeys saved in a password manager like Google's can be available on your new phone once you sign in to the same account, which is the big advantage over a code that only goes to one SIM. If you ever want a different passkey, you can't edit it. You delete the old one and create a new one from the same Passkeys menu.
Why can't I create a WhatsApp passkey?
- Your Android version is older than 9.
- No password manager is linked, or passkeys are turned off in it.
- Your phone has no screen lock.
- WhatsApp needs updating. Passkeys rolled out gradually, so older versions may not show the option.
- You're using a work-managed phone that blocks password managers.

Who should set up a passkey first
- Anyone who travels. SMS codes often arrive late or not at all when you're abroad, and a passkey doesn't depend on your mobile signal.
- Business owners using WhatsApp for customers. Losing access for a day means missed conversations, so a faster way back in matters.
- People who've been targeted before. If anyone has ever tried to trick you into sharing a WhatsApp code, remove the code from the equation.
- Parents setting up a teenager's phone. It's one less code for someone to talk them out of.
If you're none of those, set one up anyway. It takes a minute now and saves a stressful hour if you ever lose access. Pair it with a strong screen lock on your phone, because the passkey is only as safe as the device it lives on.

Is it safe?
Yes, and it's safer than the alternative. The secret part of a passkey stays on your device and is unlocked by your face, fingerprint or screen lock. Nobody can phish it out of you by text, because there's no code to read out. The flip side is that you must protect your phone: use a strong screen lock and don't let others add their fingerprint to it.
My verdict
Create a WhatsApp passkey from Settings, Account and Passkeys, and keep two-step verification on as well. Check you've got a screen lock and a password manager first, because that's why most passkey setups fail. Once it's done, you'll never wait for a verification text again.
