A shame I haven’t seen Passwordstore (pass) here. Simple, transparent, and to the point, with great extensibility to boot. It also interacts with git allowing you to version track your own storage, which is a huge plus for me since I use git daily.
On other choices, I think the largest point you should consider for a password manager is the ability to self-host your own instance. Opensourced server code is the next best thing. In security, human trust should never be trusted, and even if the company is not lazy and malignant about your data, bundling up a lot of them create obvious larger targets for potential hackers, and you have higher chance of getting the collateral damage than localized ones.
i’ll play devil’s advocate and say: None of them. Programming languages are tools, and so treat them like one is better. A better question to ask is: what are you doing to need one? Then work out the characteristic of a tool you want. E.g: you want to make a game, lets say you want to use Unity, then learning C# would be the best answer. Or you want to start with godot, maybe because it’s friendly to you, then learning go would be the obvious choice. Just pick one that you rationalized is best, doesn’t matter if it’s faulty reasoning, then go all the way with it is the best approach here imo.
