It seems a day doesn't go by when I've heard about needing to share credentials with someone else. And while I try to deny the need to do this, it just keeps on happening.
We evaluated a bunch of the ones out there and even the open source ones still didn't support Client Side Encryption. And there really is a fundamental need for that. All credentials should be encrypted on the client side before shared, and yet, for some reason none of them do this.
So we've made an open source and completely free quick solution to Share temporary credentials. The source is of course available on GitHub. It's a community edition so everything is free and no account is required.
I hope you think twice before sharing credentials, and three times before you send them over email or Slack.
