How to Migrate to Passkeys Without Losing Access to Your Accounts
A passkey replaces your password with a cryptographic key tied to your device. It's more resistant to phishing than any password, but it has a weakness that almost nobody explains: if it depends solely on your phone or computer's ecosystem, losing that device can lock you out of your account.
This guide isn't just "how to enable passkeys" — it's how to do it without getting locked out halfway through migration.
What really changes with a passkey?
The passkey eliminates the password as an entry point. Instead, your device proves your identity with a key that never leaves it — there's nothing an attacker can steal through phishing, because there's nothing to type.
If you want to understand the complete technical difference between passkeys and physical security keys, we have a dedicated comparison for that. Here we focus on the practical part: how to migrate without mistakes.
The weakness nobody tells you about
A passkey created on iPhone is saved in iCloud Keychain. One created on Android goes to Google Password Manager. If you use multiple devices from different ecosystems — an iPhone and a Windows PC, for example — the passkey doesn't always travel between them on its own.
If your only access method is a synced passkey and you lose that device, or switch ecosystems, recovering access depends on each service's recovery process — it's not always immediate.
The solution isn't to avoid passkeys. It's to not depend on a single point of failure.
Before migrating: preparation checklist
Google, Microsoft, Apple, GitHub, PayPal, and Binance already support it. Not all services have it enabled by default — check the security section of each account.
Before changing anything, check what happens if you lose access — recovery email, backup codes, phone verification.
Most services allow you to have passkey and password active at the same time during the transition. Keep both until you confirm everything works.
How to migrate without losing access, step by step
From your account's security settings, without disabling any other access method yet.
Log out and sign in again from another phone or computer. If it fails here, better to discover it now than with the password already disabled.
A physical security key works the same on any device, without depending on iCloud, Google, or Microsoft. It's the most robust backup against an ecosystem change.
Once you've confirmed that the passkey works on multiple devices and you have a backup registered.
Why a physical key works well as a backup
A YubiKey is, technically, a passkey — but physical and portable. It doesn't live in any ecosystem: it works the same on iPhone, Android, Mac, Windows, or Linux, because the key is on the USB/NFC device itself, not on any manufacturer's cloud.
It doesn't replace your synced day-to-day passkey — it complements it as an independent safety net. If you ever change phones, operating systems, or lose access to your Apple or Google account, the physical key still works the same.

What to do if you get locked out
Use the service's recovery method (email, backup codes, or support). If you have a security key registered as a backup, that's the fastest way — it only works if you registered it before losing access.
Accessories to carry your backup key
Manufactured in Spain (EU). NFC works without removing the key from the case or tray.
Keychain with Lanyard
Carry your physical passkey with you every day, protected from bumps and scratches.
Card Tray — 1 Slot
Credit card format, ideal for storing your backup key in your wallet or a safe place.
Should you migrate to passkeys now?
Yes, if the service supports it — it's more secure than a password and doesn't cost anything to activate in parallel. But don't do it without a backup: register a physical key or a second device before deleting the password.
The passkey solves phishing. The backup solves lockout. You need both.
Frequently asked questions
Can I have a password and passkey active at the same time?
Yes, on most services. It's recommended during the transition, until you confirm that the passkey works correctly on all your devices.
What happens if I lose the phone where I have my passkeys?
If they're synced in iCloud Keychain or Google Password Manager, you can recover them on a new device by signing into that account. If not, you'll depend on each service's recovery method — which is why an independent physical backup is useful.
Is a YubiKey the same as a passkey?
Technically yes — it's a passkey stored in hardware instead of a manufacturer's cloud. The difference is that it doesn't depend on any ecosystem.
Does it work the same on all services?
Not all services support passkeys yet, and implementation varies. Check the security section of each account before assuming it's available.
