Find the message you saw, or the problem, below. Messages are quoted as the app shows them.

#Signing in

We couldn't sign you in with that passkey. Try again, or use an email code or GitHub. The passkey sign-in did not complete. Try again, or sign in with an email code or GitHub. Either of those gives you a signed-in but locked session. Then unlock with a passkey. See Sign in.

This passkey needs one more unlock before it can sign you in. Use an email code or GitHub this time. A passkey set up before passkey sign-in existed needs one unlock first. Sign in another way, then unlock with it and StackHangar updates it.

This browser can't unlock your vault with that passkey. Use an email code or GitHub, then a passkey that works here or your recovery key. The browser did not return the data needed to open your vault. This can happen with a passkey on a phone used over a QR code. Use a passkey that works in this browser, or your recovery key.

Too many attempts. Wait a few minutes and try again. Sign-in, email codes and unlock attempts are rate limited. The sign-in page says how many minutes to wait.

GitHub sign-in didn't work. Make sure your GitHub email is verified, or use an email code. Verify your email on GitHub, or sign in with an email code.

You've been signed out. Reload the page to sign in again. Your session ended. Reload and sign in.

Signed out after 12 hours. or Signed out after N minutes idle. StackHangar asks you to sign in again at least every 12 hours, and signs you out after the idle time you set in Settings. Sign in again.

#Unlocking and passkeys

A locked vault is not an error. After you sign in, or after the vault locks, the unlock screen says why: Locked after N minutes idle. You're still signed in., You locked your vault. You're still signed in., or Your unlock session ended, so your vault locked. You're still signed in. Choose Unlock with passkey. See Unlock your vault.

The passkey prompt closed without a passkey, so nothing changed. Try again, and choose your phone or security key in the prompt if this device has none of your passkeys. You dismissed the prompt, or none of this device's passkeys belong to your vault. Try again and pick another device in the prompt.

That passkey isn't one of this vault's passkeys. Nothing changed. Try again with another of your passkeys. You picked a passkey that is not registered for this vault. Use another one.

This browser can't use passkeys here. Open StackHangar in a recent Chrome, Edge, Safari or Firefox. Open StackHangar in a browser with full passkey support.

This device or password manager already has a StackHangar passkey for your account. Choose a different one, such as your phone or a security key, in the prompt. Shown when you add a passkey that already exists. Choose a different device.

That didn't unlock your vault, and nothing changed. Try again. A general failure. Try again, and if it repeats, try another passkey.

#I lost a passkey

If you still have another passkey, unlock with it, then open Settings, remove the lost passkey and add a replacement. See Passkeys. If you can no longer trust the device, also rotate your vault key. See Rotate your vault key.

#I lost all my passkeys

Choose Lost your passkeys? on the unlock screen and enter your recovery key. You then create a new passkey on this device. Your other passkeys are removed, because those devices are presumed lost, and you get a new recovery key. Save it before you leave. See Recovery key.

This vault has no passkey that can unlock it. Use "Lost your passkeys?" below with your recovery key. The same path, offered when no passkey can open the vault.

That recovery key doesn't match. Check for missing groups and look-alike characters. Re-enter the key carefully. Look for a missing group of characters and for look-alike characters.

Your new passkey was added on this device, but your lost passkeys may not have been removed. Recovery stopped near the end. Press Back, choose Unlock with passkey with the new passkey, and remove the lost passkeys in Settings.

#Offline and connection problems

You're offline or we couldn't be reached. Nothing changed. Your device could not reach StackHangar. Check your connection and try again. The message means the request never arrived, so nothing was saved.

We couldn't reach StackHangar. Check your connection, then reload. Shown when the app cannot load your account. Reload when you are back online.

During first-time setup, if the connection drops, the page tells you your vault may or may not have been created. Reload when you are back online: it asks you to unlock if the vault exists, or lets you start again.
