You can set them globally or per-interface (interface options in general
are just overrides of the global per-protocol options). I'm not sure
what happens if you set both, actually.

If you want to, say, use the same key on two interfaces, but not a
third, you'd have to copy the config line to both interface configs.

There are also a bunch of per-key options, such as active times and an
ID. See the 'password' entry here:
https://bird.network.cz/?get_doc&v=20&f=bird-3.html#ss3.3

I haven't played around with this extensively, but am planning to do
that once I get around to updating the implementation to the latest
version of the draft...
