Your keys look like a long string of letters/numbers

You can go to the wallet page to see what you are logged in as. It will show you the lesser keys if you are logged in with a higher key.

You probably are logging in through HIVE-keychain, and that thing probably has your keys, but i do not know if it will show them to you.

But, if you truly do not have your keys, the only way to get them back is account recovery. And that requires some know how. It is not straight forward.

Or you can just start a new account
