Direct answer

Send an API key securely by putting the existing key or token into an encrypted expiring link instead of pasting it into Slack, email, issue trackers, or support tickets.

What to avoid

Posting API keys in team chat where history is searchable.
Adding tokens to issue trackers or pull request comments.
Sending long-lived production keys without rotation planning.

Safer workflow

1 Paste the existing API key, access token, or secret key.
2 Use one view and the shortest practical expiration.
3 Send the generated link only to the person who needs the key.
4 Rotate or revoke the key after temporary access is no longer needed.

Unsafe channel vs safer delivery

Common approach

Safer Secret Pusher approach

API key in a chat thread

Deliver the key through a one-view encrypted link.

Token in a support ticket

Paste the Secret Pusher URL into the ticket instead.

FAQ

Does this generate API keys?

No. It securely sends an existing API key or token.

Why not send API keys in Slack?

Chat history is searchable and persistent. An expiring encrypted link limits long-term exposure.

Can the link be one-time only?

Yes. One view is the default.
