Want a secret that only opens with a key in hand, even if the link is forwarded? Protect it with a passkey.
Open Passkeys and click New passkey. If the key is with you, choose Local.
Give it a name, click Create key, and touch the key when your browser asks.
It's now in your Passkeys list.
Now create a secret. Turn on Advanced mode, type the secret, and open Auth.
Choose Passkey, and pick the key you just added.
Then SharePass it, and hand the key to the person who will open the secret.
To open the secret, they touch the key. Without it, the link shows nothing.
Passkeys come with the Business plan. Find out more at sharepass.com.
