Multiple private keys not handled correctly?

Hi @neun34tel:

Generally speaking, this would depend on the specific configuration of the SSH server you're connecting to. OpenSSH's default is 6 keys can be presented before disconnecting, but this can be changed, and it seems like this server has been configured to accept less keys before disconnecting. In this case, your best bet would be to configure SSH on your machine to always use that key for that server.

To do this, first download the public key for the keypair you'd like to use from 1Password for Linux.

Place the public key in your ~/.ssh/ directory, and give it a name like thirdkey.pub. In your ~/.ssh/config file, add a snippet that looks something like this:


Host <mythirdrepo.com>
IdentityFile ~/.ssh/thirdkey.pub
IdentitiesOnly yes

At this point, the remote of git@ will use your third key.

If all of your repos are on the same host, the snippet would instead need to look something like this:


Host thirdrepo
HostName <example.com>
User git
IdentityFile ~/.ssh/thirdkey.pub
IdentitiesOnly yes


Then for your Git remote, rather than using git@:user/repo.git, you'd use thirdrepo:user/repo.git. Let me know how you get on with that!

Hi, Jack!

Thanks for the answer. I just had the time to try it. Sorry I'm so late.

It was possible to set it up so the correct key seems to be used, but now I get
Load key "/path/to/publickey.pub": invalid format.

The public key was downloaded (not copied) from 1Password on SteamOS (I try to set it up on my Steam Deck in Desktop mode).

Hi @neun34tel,
Did you find how to fix this error? I think I followed the same way as you, but the result the same and auth not working...
@Jack.P_1P, if you have a solution too... :x

Hi @Hobbyvores and @Jack_P_1P!

The problem still persists for me as well.
