Your permissions or lesser keys haven't changed since June 2020 and your owner key hasn't changed since making the account, so if you still have those keys it shouldn't be an issue.

Monochromes' suggestion of using Keychain is a good idea. And using PeakLock to log in with your posting key makes it smoother to use. That way you only have to use Keychain to do active key transactions.

It's good to see you back!
