You need to send someone a password. Maybe a Wi-Fi password, an API key for a colleague, or a Netflix login for your partner. What do you do?
Most people text it. Or email it. Or put it in a Slack message. All of these are terrible ideas.
SMS is plain text. Your carrier can read it. Anyone who intercepts it can read it. And it lives on both phones forever.
You send a password by email. Now it exists in your Sent folder, their Inbox, your email server, their email server, and every backup of both.
Every message in Slack is indexed. Search "password" in your workspace. You will be surprised what shows up.
The only safe way to share a password is to make it disappear after it is read.
Lockbox Whisper encrypts your secret, creates a one-time link, and destroys it after the recipient views it. The recipient does not need an app or an account. They just click a link.
Open Lockbox and tap Whisper
Type or paste the password you want to share
Optionally add a PIN for extra protection
Tap Create Whisper to get a link
Send the link via text, email, Slack, anything
They open it, see the password, and it self-destructs
Great question. The decryption key is in the URL fragment (the part after the # symbol). Per internet standards (RFC 3986), the fragment is never sent to the server. Our server only sees encrypted noise. The decryption happens entirely in the recipient's browser.
Even if someone intercepts the link, the whisper self-destructs after the first view. The interceptor would need to open it before the intended recipient does.
Both have sharing features, but both require the recipient to have an account. If you are sharing a password with your mom, your contractor, or a client, asking them to sign up for a password manager just to receive one password is not realistic.
Lockbox Whisper requires nothing from the recipient. No app. No account. No sign-up. Just a browser.
Whisper is included free. Unlimited self-destructing links.
