Can't SSH Key

[Lakshit Singh Bisht]

"error - key: Someone has already added that SSH key."

I am getting this error while adding my ssh key for signing commits. 

1. Technically I can use same key for multiple purpose, so why is bitbucket showing it?

2. I have added same key in Github, Gitlab, Codeberg, and Gitea. There no problem and commits are signed automatically

Hello @Lakshit Singh Bisht 

Bitbucket requires SSH keys to be globally unique. This error means your key is already registered somewhere else in Bitbucket Cloud (e.g., another account, workspace, or repository access key).

If this key is already linked to your personal account for authentication, you don't need to add it again for commit signing. Otherwise, the fastest is to generate a new SSH key pair which is also a security best practice for easier rotation.

Best,
