Amazon passkey: how to set one up and sign in with it
SHORT ANSWER
How do I set up a passkey for Amazon?
Amazon's help says to open Your Account, choose Login and security, and select Set up next to Passkey, then follow the prompts. The passkey is saved in your device's passkey provider and you unlock it with a fingerprint, face or screen lock instead of typing a password.
Key takeaways
- Amazon lets you add a passkey under Your Account, then Login and security.
- The passkey is saved by a passkey provider on your device, not by Amazon, and is unlocked with your biometric or screen lock.
- Keep another way to sign in until you are sure the passkey works.
- Which providers a site accepts is up to the site and your device. Check before relying on one.
Disclosure: HostSpica makes HostSpica Identity, an Android app that is also a passkey provider. Facts about other services come from their own help pages, checked on 4 October 2026, and can change.
What an Amazon passkey is
A passkey replaces the password for one account with a cryptographic key pair. The private key stays on your device, the public key goes to Amazon, and signing in means proving you hold the private key. A fake Amazon page cannot use it because the key is tied to the real site's address. For the full picture see passkeys from first principles.
Set it up
- Sign in to Amazon on a phone or computer.
- Open Your Account and then Login and security. Amazon's help describes this path, though menu names can change.
- Next to Passkey, choose Set up and follow the prompts.
- When your device asks where to save the passkey, pick a provider you trust and approve with your fingerprint, face or screen lock.
- Sign out and sign back in with the passkey to check it works.
Where it is saved matters
| Saved in | Who can use it | If you lose the phone |
|---|---|---|
| Google Password Manager | Your Google account on Android and Chrome | Restores with the Google account |
| iCloud Keychain | Your Apple devices | Restores with the Apple account |
| HostSpica Identity | That one Android phone only | Gone with the phone. Sign in another way and add a new passkey. |
HostSpica Identity keeps passkeys on the device behind Android Keystore, with no cloud sync. That is a deliberate trade-off: nothing leaves the phone, but nothing can be restored either. See what to do if you lose your phone.
Using HostSpica Identity with Amazon
HostSpica Identity needs Android 14 or newer for passkeys. Its Google Play release is in the final steps as of 4 October 2026, so check the app page for the live link.
Amazon decides which providers it accepts and how its prompts look. We have tested HostSpica Identity passkeys on Google, GitHub, Microsoft and webauthn.io in Chrome and Brave, including creating a passkey, signing in and the duplicate-passkey check. We have not tested every site, and no site is guaranteed to accept it. Amazon is not on that list, so we cannot promise it works. If the prompt does not offer HostSpica Identity, use another provider for Amazon.
Frequently asked questions
Does Amazon support passkeys?
Yes. Amazon's customer service has an About Passkey page and a Set up option under Login and security.
Can I use an Amazon passkey on another phone?
Only if your provider syncs it, as Google Password Manager and iCloud Keychain do. A device-only provider such as HostSpica Identity does not.
Is a passkey safer than my Amazon password?
It resists phishing and cannot be reused or guessed, but it does not help if someone can unlock your phone. Keep a strong screen lock.
What if I lose the phone with my Amazon passkey?
Use another sign-in method or Amazon's account recovery, then add a new passkey on your new phone.
