Can You Share a Passkey With Your Team?

By Kalpesh Mahida · Updated August 29, 2026

Can you share a passkey with your team? The honest answer is: it depends on the kind of passkey. Some passkeys can never leave the device they were made on. Others are built to sync and can be shared through an encrypted vault. This guide explains the difference, how teams actually share a passkey, and what sharing does and does not change about security.

Why most passkeys cannot be shared

A passkey is a private key that proves you hold a specific device. A passkey you create with Touch ID lives in the Apple secure enclave. One created with a YubiKey lives on that key. These are hardware-bound and non-exportable on purpose. That non-exportability is the security property that makes passkeys phishing-resistant. It is not a bug you can work around, and no legitimate tool can pull an existing hardware or platform passkey off its device.

The exception: software and synced passkeys

Not every passkey is hardware-bound. A software passkey, created and held by a password manager rather than the device secure enclave, can be synced across devices and, with the right tool, sealed and shared. This is the category that makes team sharing possible. The passkey is still a phishing-resistant credential. What differs is where the private key lives: in an encrypted vault you control rather than one person hardware.

How teams actually share a passkey

There are two practical paths in 2026.

A full password manager shared vault

The major managers can store a software passkey and share it through a team vault or shared folder. Good if your team already runs one. The cost is that you take on a whole suite, and team sharing usually sits behind a paid organization plan.

A single-purpose shared-login tool

A focused tool shares one login without the suite. Coauth, the tool I build, is a free Chrome extension that registers a software passkey through the browser, seals it to each teammate, and lets everyone sign in from their own device. No account needed to start, and no per-seat cost to share.

What sharing changes, and what it does not

Sharing a passkey does not weaken the factor. Every member still authenticates with a phishing-resistant passkey, and the login stays bound to its origin, so it is not phishable. What you give up is per-user attribution: when several people use one shared credential, the account cannot tell them apart. That is fine for a genuine service account and wrong for anything that needs an individual audit trail. Share service accounts, keep named users individual.

How to share a passkey with Coauth

1. Install Coauth and secure your vault with your device passkey.
2. Register a new passkey for the account through Coauth. An existing hardware or platform passkey cannot be exported, so you add a fresh software one.
3. Create a team and share that passkey into it.
4. Invite teammates. The shared passkey appears in their vault and signs in from their own browser.
5. Remove anyone who leaves. The team key rotates so their copy stops working.

When you should not share a passkey

If each person needs their own access and audit trail, do not share. Give each user their own account and their own passkey. Sharing is for accounts that are genuinely one shared identity, a service account, a shared admin login for a small team, a short-term contractor. Use it on purpose, not as the default.
