I don't want to be that one who points it out, but - how about switching to the password-store [0] (or gopass [1] - way easier), which works under all operating systems and keeps secrets versioned (via git).
With pass(1) you name your credentials accordingly to their purpose. For example, you could use following naming pattern: [client-name]/[website/subject]/[secret-name]. e.g. acme-corp/github.com/ssh/public-key, other-client/github.com/account, personal/gmail.com/password etc. That way, removal of old/unused secrets is just simple as doing "gopass rm -r [client-name]". There are also many more commands to list or print a tree of stored credentials.
Generally speaking, pass(1)/gopass(1) is a very simple way to manage credentials. I can't say how much I recommend that flow instead of using KeePass or plain-text files. Additionally, if you need those secrets on mobile phone there is an Android app [2] that might be very handy in some situations. This Android app and also gopass(1), have OTP code calculator (similar as in Google Authenticator), so you might be more happier with adapting yourself to use 2FA.
