CredenShare vs Privnote

The short answer

• Privnote is a free, ad-funded web service for notes that self-destruct after reading, with no account needed.
• CredenShare is built for sharing credentials at work: passcodes, an access log for every share, teams, integrations, and Secure Requests to collect credentials.
• Use Privnote for a quick personal note. Use CredenShare when the credential is a work credential.

What does each tool do?

Privnote creates a link to a note that is destroyed after it's read, or after a set time: 1 hour, 24 hours, 7 days or 30 days. With a set time, the note can be opened any number of times until it expires. Unread notes are removed after 30 days. It needs no registration, and can email you when the note is destroyed. It has no teams, API or requests.

CredenShare sends credentials through encrypted links that expire, records every view, and collects credentials through Secure Requests, with teams, Slack, a browser extension and an API.

Where is your secret encrypted?

• Privnote generates the link in your browser, and the link holds the decryption key; its privacy policy says the link is never sent to Privnote, so nobody there can read a note. You can add a manual password. It says it doesn't log IP addresses.

• CredenShare: Shares created in the web app, through the API or with the SDKs are encrypted in your browser or client with AES-256-GCM, using a key made for that share alone; the key travels in the part of the link after the #, which browsers don't send to servers. Shares created from Slack are the exception: they're encrypted on our servers.

What does CredenShare add?

Links that fit how people work

Expiry from 1 hour to 3 months, optionally counted from the first open, with one, several or unlimited views, a passcode (Solo and above) with a failed-attempt limit, required sign-in, and IP allowlists (Business and Enterprise).

A record of every handoff

Each share logs the time and IP address of every view, kept for 3 to 180 days depending on your plan (not on Free). When someone says the credential never arrived, you can check.

Credentials coming back to you

Secure Requests (Business and Enterprise) send a form with the fields you choose. The submitter's browser encrypts each answer to a key belonging to the request, and you can require them to sign in with two-factor authentication.

Teams and integrations

Teams share an allowance, with optional zero-knowledge custody (Business and Enterprise). Create shares from Slack (Plus and above), a browser extension for Chrome and Firefox, or code: a REST API, SDKs for Node, Python, Go and Rust, an MCP server for AI agents, and webhooks.

What does each cost?

Privnote is free and funded by ads. CredenShare: Free (3 shares a day); Solo $9.99/month (passcodes, access logs); Plus $49.99/month (5 seats, teams, Slack); Business $99.99/month (Secure Requests, API, IP allowlists). Yearly billing: $99.99, $499.99 and $999.99. See pricing.

Which should you use?

What to ask any secret-sharing tool before you trust it

1. Where is the secret encrypted? In your browser, or on the provider's servers after it arrives? Browser-side encryption means the provider never holds a readable copy.
2. Who holds the key? If it's in the link (after the #), the server can't decrypt without the link. If it's on the server, the provider can.
3. What happens to link previews? Email and chat scanners can open links. Can you allow two views, or start the clock at the first open?
4. Can you prove it arrived? Is there a record of each view, with a time and an IP address?
5. How long is data kept after expiry? What is deleted, and what metadata remains?
6. Can people send secrets to you? Without a request feature, credentials still arrive by email.
7. Where is it hosted, and can you self-host? That matters for data-residency rules.
8. Who on your team can see what? Admin visibility, team ownership, and what happens when someone leaves.

How do you switch from Privnote to CredenShare?

There's nothing to migrate: sharing links are short-lived by design.

1. Create a CredenShare account. The Free plan covers 3 shares a day.
2. Send your next credential with CredenShare: fill in the fields, set an expiry and a view limit, and add a passcode on a paid plan.
3. Invite your team (Basic and above), and add the Slack app, browser extension or SDKs you'll use.
4. Replace "send me your password" emails with Secure Requests (Business and Enterprise).
5. Let existing Privnote links expire on their own.

Where Privnote is the better choice

• No account at all: anyone can create a note.
• Free, with nothing to set up.
• An email when the note is destroyed.

Before you share a credential: a checklist

These apply whichever tool you use.

1. Send the link and the passcode through different channels. For example, the link by email and the passcode by text message.
2. Watch out for link scanners. Some email security filters and chat apps open links automatically, which can use up a one-view link. Send the link as plain text through a channel that doesn't pre-open links, or allow a second view with a short expiry.
3. Don't open the link to test it. On a one-view link, your test is the view.
4. Pick the shortest expiry that works. If you don't know when the recipient will act, a link that starts counting at the first open is safer than a long fixed window.
5. Rotate after the handoff when you can. The link expires, but the credential is still valid.
6. Keep the original in your password manager. A sharing link is a delivery method, not storage.

Verdict

Privnote is a simple, free way to send a note that disappears. For work credentials, where you need a passcode, a record of who opened what, team control, or credentials coming back to you, CredenShare is built for the job.
