Pff, such capitalist bull. But communists at least have LastPass, that shares our passwords with the world under the banner of no private ownership.
But seriously, paying for a password manager is a good thing. Find a good and secure one that is properly vetted and trusted in the industry, and support them if you can.
You better have created a Keyfile with it and store that only locally on your devices, otherwise if your passwords get leaked or you get hacked it is 100% your fault and not Dropbox's fault.
