How to Share API Keys Securely

Verify the recipient, create a scoped credential, and send it through an encrypted one-time link instead of pasting it into chat. After handoff, store the key securely and revoke it at the provider when access ends.

The encrypted payload is deleted after this time or after the first reveal.

Get an email when the secret is accessed. Your address is stored until access or expiry and shared with the mail provider for delivery.

How Does a Secure API Key Handoff Work?

  1. Create the right credential

    Use a separate development or contractor key with only the required permissions, where supported. Record its owner and planned revocation date without recording the secret value.

  2. Verify the recipient

    Confirm who needs access using a trusted contact method. Prefer granting access in your existing secrets manager when your team already uses one.

  3. Create an encrypted, expiring link

    Paste the key into the form above and choose the shortest practical expiry. SnapPwd encrypts the message in your browser before uploading it.

  4. Send the link privately

    Send the complete link only to the intended recipient. With the separate-key option, deliver the decryption key through a different trusted channel. Do not reveal the secret yourself to test the link.

  5. Store the key and close out access

    The recipient reveals the message and saves the key in approved storage. Revoke the provider credential when access ends; deleting a delivery link does not revoke a copied key.

For storage and revocation, follow our API key management checklist. For multiple setup values, see how to share .env files.

What Does SnapPwd Protect During Delivery?

Zero-Knowledge Encryption

Your API keys are encrypted in your browser before upload. By default, the decryption key is carried in the link fragment, which is not sent in the HTTP request.

One-Time Access Links

The stored message is deleted after retrieval or expires at the selected time. Recipients can still save the revealed API key.

No Registration Required

Share securely in seconds without creating an account. No email verification, password management, or lengthy signup process.

Built for Teams

Use a one-time handoff for onboarding and contractor setup. Verify who receives the link and keep ongoing permissions in the API provider or your secrets manager.

Common API Key Sharing Use Cases

Third-Party API Integration

Share API keys for services like Stripe, Twilio, Google Maps, or any external API with your development team.

Contractor Access

Deliver a scoped credential to a contractor, then revoke it at the provider when the engagement ends. Link expiry does not limit API access.

Development & Testing

Share test API keys for development environments without risking production credentials.

Service Account Keys

Securely distribute service account keys, OAuth tokens, and other authentication credentials.

API Key Security Best Practices

Sharing is only one part of API key security. Teams also need safe API key storage, rotation, least-privilege permissions, and a clear response plan for exposed credentials.

Why Traditional Tools Fall Short

Email Risks

  • • Copies in inboxes and backups
  • • Accidental forwarding
  • • Searchable by all recipients
  • • No credential revocation

Chat Platform Risks

  • • Retention depends on workspace policy
  • • Easy screenshot sharing
  • • Search by people with channel access
  • • Copied keys remain usable

SnapPwd Difference

  • • Single-use access links
  • • Stored message expires or is consumed
  • • End-to-end encryption
  • • Recipients can still retain copies

API Key Sharing FAQ

How do I share an API key securely with a teammate?

Prefer a separate, scoped credential for each teammate when the provider supports it. If a key must be handed over, verify the recipient, use an encrypted one-time link with a short expiry, and have them store it in an approved secrets manager.

Does an expired SnapPwd link revoke the API key?

No. Link expiration ends access to the stored message. A copied API key remains usable until it expires or you revoke it with its provider. Revoke contractor credentials when their access ends.

Can I send the link in Slack or email?

You can send a link instead of pasting the raw credential. Treat the complete link as a secret: anyone with it may reveal the key before the intended recipient. Verify the recipient and avoid public channels. A one-time link cannot prevent copying or screenshots after reveal.

Should my application load API keys from a one-time link?

No. One-time links are for a human handoff. Applications and CI jobs need a secrets manager or platform secret store for repeatable runtime access, access controls, and rotation.
