Linux passwords, database passwords, third-party system passwords, mail passwords... At some point they have to be written down somewhere, and the possibility of a plain text file leaking online gives me the creeps. Manual encryptation means that at some point (while editing) it exists unencrypted on disk, and a leak could happen (a backup copy of your text editor, for example).
I am not talking about browser plugins that can help only with web-based interfaces. The mix-up of interfaces means that at some point you have to write them down, securely. How are you guys doing it?
