There are a lot of password management solutions so here we will focus on the most common.
Here we are specifically hilighting high level security/usability attributes of each, and specifically which have support for things like hardware token encryption/signing/2FA, and those that do not.
What should I use?
The password manager that checks the most security and compatibility boxes above is Password Store, so the instructions below will focus on that. If you don't maintain highly sensitive credentials perhaps the tradeoffs of another tool will work better for you. Any password manager is better than trusting memory, a text file on your machine, or post-it-notes.
Pass will by no means suit all use cases, as there is no one-size-fits-all hero in password management tools right now. You are encouraged to do your own research.
It is worth noting that while Pass may check the most boxes, it may be one of the most difficult to set up initially and you will have to factor the technical capability of yourself or users you support into consideration.
With those disclaimers out of the way, the reason Password Store supports everything is that both the CLI tools and GUIs like Android Password Store and QTPass all share a very simple common understanding of how passwords should be encrypted, stored and interacted with under the hood.
A Password Store repository is just GPG encrypted text files in a folder. Optionally "pass" tools all support that folder being managed via Git, and can wrap git commands and sync for you. This allows for a very simple and easy to reason about password management strategy, that does not require any specialized tools except for convenience.
If you GPG encrypt a text file and put it in a folder, any "Pass" compatible program will consider that folder to be a valid password store.
The source code of the reference CLI implementation of pass is nothing but a simple bash script that wraps gpg and git commands making it easy to audit and trust. You can however always manually decrypt pass with just GPG as you like to integrate with any tooling you need.
There is always a new flavor of the week when it comes to password managers however gpg makes for a very simple and predictable backend that has been maintained and audited by governments and the open source community since 1999.
- A hardware token with GPG
- Git configured to sign all commits
Set up a Git remote you can access from anywhere
Github example via 'hub':
$ hub create -p passdb
Obtain your long-form GPG Public Key ID:
$ gpg --list-keys --with-colons tru::1:1481584702:1510091812:3:1:5 pub:u:4096:1:E90A401336C8AAA9:1241834622:1510091812::u:::scESCA::::::: fpr:::::::::6B61ECD76088748C70590D55E90A401336C8AAA9: uid:u::::1447019812::1001C6683FA88F0D1AE082F4C55F84C687FD2732:: John H Doe <email@example.com>: ...
Initialize Password Store with your GPG ID and Git Remote
pass init "6B61ECD76088748C70590D55E90A401336C8AAA9" pass git init pass git remote add origin "firstname.lastname@example.org:your-user/passdb.git"
Set your first password
This will generate a random 50 character password, gpg encrypt it to your key, and save it as ~/.password-store/Personal/gmail.gpg
It will then make a commit on your behalf to the repo defined at ~/.password-store/.
Your Security Token should ideally begin blinking so you can touch an approve it signing the commit for you.
pass generate Personal/gmail 50
Sync to Git Remote
pass git push
Graphical user interface for pass that supports Linux, BSD, OSX, and Windows
Very simple dmenu based GUI for pass on Linux and BSD that supports keyboard emulation via xdotool to auto-type passwords on demand.
This allows a sweet spot of ease of use without relying on the system clipboard or complex browser plugins that introduce additional attack surface.
Ships with "pass" package on most unix/linux distributions.
Android Password Store
Provides a GUI for Android that can add/remove/modify/sync passwords against your remote Git repo.
Supports NFC or USB OTG Security Tokens via OpenKeychain.
Android Password Store: https://f-droid.org/packages/com.zeapo.pwdstore/
Provides a GUI for iOS that can add/remove/modify/sync passwords against your remote Git repo.
