How did all the passwords get in my login keyring?

Question

In my Passwords and Keys application (Seahorse) I have a "login" keyring. Within that are a many keys. How did they get there? What application put them there? I use Chrome with Lastpass extension, would that do it?

Seahorse is the tool to manage keys and passwords. (See seahorse manual.)
