argon2-browser VS pass-import

It works by the way on CLI and mobile, and mobile is especially slow on some low-end android devices. It *should* also be possible to make parallelism work for the WebAssembly version, but for some reason the issues with threading were never ironed out. I'm not sure whether it's worth investigating that, or to just add SIMD support where possible, and wait for webcrypto to add argon2.

Notice how they don't provide any benchmarks that aren't Native or WASM?

This doesn't help iOS users in Lockdown mode. It may also break for users who run their OS in FIPS mode.

Ideally I'd like to use something like of argon2 to derive my key because that's the de facto best algorithm for the purpose. There are a few WASM ports of it but they don't seem maintained and they don't play nice with the bundler I'm using.

> is there really fast enough implementations available to the browser

Browsers have pretty good support for surfacing native code SHA family hash functions which you can use to speed up PBKDF2. It's called the Web Crypto API and it's available even in Internet Explorer 11. [1]

If you're willing to drop support for IE11 and older phones like the iPhone 4S, then you get access to WebAssembly. With WASM you can get a bunch of custom algorithms to be quite fast. The Argon2 browser WASM library claims to be only about 10x slower than optimized native code. [2]

It's not perfect, but it isn't as bad as it used to be with just pure JavaScript.

> I always tell these people to just sign up for a password manager and they always resist and say no. I must be missing something obvious.

Maybe they don't want to be relying on a random third-party for all their passwords?

Rather than getting them to sign up for a password manager, what about getting them to install a password manager? I use https://www.passwordstore.org/ - it encrypts your passwords with GPG, and shares the storage via a Git repository for synchronisation between different machines.

That way you can delegate the password handling to another program, e.g. a password manager like pass(1) (https://www.passwordstore.org/) or some interactive graphical prompt.

I want to move to something compatible with https://www.passwordstore.org/ - an open standard for keeping your passwords in a folder encrypted with OpenPGP.

The problem is that I'm nervous to give an unknown Android app and browser plugin total control of my passwords and access to my github account when I don't have time to review it's code properly. I have a bit more trust ing the command line tools, but I'd like to be sure that more people are looking at the code before I trust my life to it.

> Create a system or pattern based on url or brand and mentally hash it into a password.

Doesn't sound very secure. Also when you realize that you anyway have to trust cryptography, I believe it starts making a lot of sense to have an actual cryptographic key and encrypt it with one good random password you learn by heart.

I use pass https://www.passwordstore.org/, which encrypts my passwords with my GPG key, which comes from my Yubikey, which I unlock with a password. That means that I only need to remember one password, and it feels a lot more secure than your pattern based on url or brand.

i use pass and keep my database on a local git repo. it encrypts your passwords with gpg and is a really simple command line program

If you want portability and simplicity, there's a project called simply pass that uses standard *nix utilities (and git, I believe) to manage passwords from CLI.

0. Pass is just text files encrypted with gpg. I needed just one password on one work computer, where I had my gpg key, but not all my passwords. Decrypted the file and that was it.

1. There are plugins and web clients: https://www.passwordstore.org/#extensions

I've been incredibly happy with https://www.passwordstore.org/ for years. The data store is a file hierarchy, with the files themselves encrypted with GPG. Sync is via git. TOTP support with a plugin.
