Why even enabling such a feature? I have my own personal account and a team account. I would like to use my ssh key on both of them!

+1 ... The mind boggles. As if working from home isn't painful enough.

Without some security explanation this is terrible terrible annoying design.

You are doing it wrong! You should not be sharing SSH keys. Generate a second one. Sharing SSH keys is worse than sharing passwords.

An SSH key is your username and password, all wrapped into one.

If you use the same SSH key on accounts, how would BitBucket know which user was performing the action? Which set of permissions to give them? It's dangerous.

in this case the user it's me, nothing else.
