Share Passwords Securely with Encrypted One-Time Links
Stop pasting passwords into Slack messages, emails, and spreadsheets where they sit indefinitely. pil.rosproc.win lets you share a password securely through an encrypted secret link that self-destructs after the recipient reads it. Send a password, API key, or any secret — it is encrypted in your browser using AES-256-GCM before it ever touches the server. No signup, no account, completely free.
End-to-end encrypted
Your password is encrypted in the browser. The server stores only ciphertext it cannot read.
Self-destructing link
The link burns after reading by default. Once its allowed views are used, the password is permanently deleted.
Zero-knowledge
The decryption key stays in the URL fragment and never reaches the server. We cannot read your password.
Optional passphrase
Add a second factor so the link alone is not enough to decrypt the password.
The worst ways to share a password (and why)
Security auditors flag the same channels over and over. Every one of them keeps a copy of your password long after the moment it was needed:
- Slack or Teams DMs — retained by the workspace, indexed and searchable. Admins and compliance tools can read direct messages, and exports keep them forever.
- Email — stored indefinitely in both inboxes, on mail servers, and in backup archives that persist for years, even after you delete the message.
- Shared spreadsheets — the classic passwords.xlsx: no access control, no audit trail, shared with people who should never have seen it.
- SMS and iMessage — no cross-platform encryption guarantee, backed up to cloud services, and visible in plain text on lock-screen notifications.
- Sticky notes and whiteboards — a plaintext password anyone walking past can read or photograph.
This is not theoretical: breaches have started from an attacker compromising a single chat account and finding credentials shared months earlier in a message nobody remembered to delete. The pattern is always the same — the password outlived the handoff. The fix is a channel where it cannot: a link that works once, then destroys itself.
Every way to share a password, compared
| Method | Setup | Works with anyone | Cost | Deletes itself |
|---|---|---|---|---|
| One-time encrypted link | None | ✓ | Free | ✓ |
| Password manager shared vault | Hours | ~ both need accounts | $3–8/user/mo | ✗ |
| Secrets manager (Vault, etc.) | Days | ✗ internal only | Varies | ✗ |
| Encrypted email (PGP) | Hours | ✗ both need keys | Free | ✗ |
| Plain email / chat / SMS | None | ✓ | Free | ✗ persists forever |
In practice, teams end up with a combination: a password manager for day-to-day internal credentials, a secrets manager for infrastructure, and one-time links for everything else — especially handoffs to people outside the organization, where shared vaults and PGP keys are impractical.
How secure password sharing works
Paste your password above and click "Create secret link". Your browser generates a random encryption key, encrypts the password with AES-256-GCM, and sends only the ciphertext to the server. The encryption key is placed in the URL fragment (the part after the # symbol), which browsers never transmit to servers. You send the full link to the recipient. When they open it, their browser fetches the ciphertext, decrypts it locally, and the server permanently deletes its copy. The password is never visible to anyone except the sender and recipient.
How to share a password with…
…a client or external contractor
Paste the credentials above and set a short expiry (1 day is usually enough). Add a passphrase, send the link by email, and tell them the passphrase on a call or in chat — two channels, so neither one alone is enough. When they have logged in, the link is already dead.
…a new hire
Before their password manager seat exists, first-day credentials still have to travel. Send each one as a one-time link in your welcome email or chat. Everything they receive works once and disappears — nothing to clean out of the onboarding thread later. When the manager seat is live, move ongoing credentials there.
…a family member
WiFi keys, streaming logins, the router password for the person fixing your internet: paste, create, text them the link. No accounts, no app to install — it opens in any browser, shows the password once, and is gone. For WiFi specifically, our WiFi password generator creates a strong key and shares it in the same flow.
…your team, right now
When something urgent has to move and the "proper" channel is a form and two approvals: one-time link in the team channel, passphrase in the standup. The chat log ends up holding a dead URL instead of a live credential. For recurring team access, graduate to a shared vault — see the comparison above.
Is it safe to share a password over email, Slack, or SMS?
Not directly — every one of those channels stores messages long-term. But here is the twist: they are all fine for sending a one-time link. Because the password is encrypted before it leaves your browser and the link dies after one view, the channel only ever carries a URL that stops working the moment it is used. Send the link over email, Slack, Teams, SMS, WhatsApp — even a post-it note. If interception worries you, add a passphrase and send it through a different channel than the link; then neither channel alone is enough to reveal anything.
Password sharing best practices
- Never send the password itself through a persistent channel. Send a one-time link; let the channel keep a dead URL, not a live credential.
- Use the shortest expiry that works. If the recipient will read it in five minutes, the link does not need to live for a week.
- Split the link and the passphrase across channels. Link by email, passphrase by phone — neither alone is useful.
- Never reuse passwords. Generate a unique, strong password for every account before you share it.
- Rotate after the handoff ends. When a contractor finishes or someone leaves the team, change what they had.
- Turn on two-factor authentication everywhere it exists — a leaked password is useless without the second factor.
When to use one-time links vs a password manager
Password managers like 1Password and Bitwarden are the right tool for ongoing shared access within a team. But they require both parties to have accounts and be part of the same organization. One-time links are better for situations where a password manager is impractical:
- Onboarding a new hire who does not have a password manager account yet.
- Sharing credentials with a client or external contractor.
- Sending a WiFi password to a guest or Airbnb visitor.
- Handing off API keys to a developer on another team.
- Any one-time handoff where the recipient does not need permanent access.
Key terms, briefly defined
- Secret link
- A one-time URL that reveals a password or secret once by default, then permanently deletes it. Also called a one-time secret link.
- Password sharing
- Sending a credential to another person. Done securely, the password is encrypted before it leaves your device and is never stored in plaintext anywhere.
- Secure share
- Sharing a secret so that only the intended recipient can read it once — the link self-destructs after a single view and leaves no copy behind.
- Zero-knowledge
- The server stores only ciphertext it cannot decrypt. The key lives in the URL fragment and never reaches the server, so we can never read what you share.
Frequently asked questions
How do I share a password securely?
Paste the password above, click "Create secret link", and send the link to the recipient. The password is encrypted in your browser before being stored. The recipient opens the link, sees the password once, and the data is permanently deleted from the server. That burn-after-reading behaviour is the default; for text you can also allow 3, 5, or 10 views.
What is the safest way to send a password to someone?
The safest way to send a password is an encrypted one-time link instead of typing it into email, chat, or SMS. Create a secret link here, share the link, and it works once by default — the password is encrypted in your browser, never stored in plaintext, and deleted after the recipient reads it, so it never lingers in any inbox or message history.
Is it safe to send a password by text message (SMS)?
No. SMS is not end-to-end encrypted, messages are stored by carriers and backed up to cloud services, and passwords appear in plain text on lock-screen notifications. If SMS is the only channel you share, send a one-time encrypted link by text instead of the password itself — the link works once by default and the password never appears in the message history.
How do I send a password through email safely?
Never put the password itself in an email — messages persist in both inboxes, on mail servers, and in backups for years. Instead, create an encrypted one-time link and email that. The email then contains no password: just a link that works once by default and then dies. For extra protection, add a passphrase and share it through a different channel, such as a phone call.
What is the best way to share passwords with your team?
For ongoing shared access, a team password manager (1Password, Bitwarden) is the right tool. For one-off handoffs — onboarding someone before they have a manager seat, sending credentials to a contractor or client, or sharing with a team that uses a different tool — an encrypted one-time link is faster and leaves no copy behind in chat history.
Can I share a password without a password manager?
Yes. A one-time encrypted link requires no accounts on either side: paste the password, send the link, and the recipient opens it once in any browser. It is the simplest secure option when one or both people do not use a password manager.
What is a secret link?
A secret link (or one-time secret link) is a URL that reveals a password or secret once by default. After the recipient opens it, the encrypted data is permanently deleted and the link stops working. If a few people need the same secret, you can choose a small view limit; the data is then deleted after the final allowed view. It is the simplest way to share a password securely without leaving a copy behind on any server.
Is it safe to send passwords over email or Slack?
No. Emails are stored indefinitely on mail servers, and Slack messages persist in searchable history that admins can export. Both channels leave your password exposed long after it was shared. One-time encrypted links solve this: the password is encrypted end-to-end and destroyed after a single view by default.
Can the server see my password?
No. Your password is encrypted in the browser using AES-256-GCM before it reaches the server. The decryption key stays in the URL fragment, which is never sent to the server. This is called zero-knowledge architecture — we cannot read your secrets even if we wanted to.
What happens after the recipient reads the password?
On a default one-time link the encrypted data is permanently deleted from the server and the link stops working immediately, so nobody — including the sender — can retrieve the password again. If you allowed several views, the link keeps working until the last one is used and then is deleted the same way; the reader is always told how many views remain. If the link is never opened, it expires automatically after the set time period (1 hour to 30 days).
Can I add extra protection to the shared password?
Yes. You can set an additional passphrase when creating the link. The recipient will need both the link and the passphrase to decrypt the password. This adds a second factor in case the link is intercepted.
Is this better than using a password manager for sharing?
They serve different purposes. Password managers are best for ongoing shared access within a team. One-time links are better for one-off handoffs: onboarding a new team member, sending credentials to a client, sharing a WiFi password with a guest, or any situation where the recipient does not need permanent access.
