A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Why self host a password manager? (programming.dev)

I'm going to move away from lastpass because the user experience is pretty fucking shit. I was going to look at 1pass as I use it a lot at work and so know it. However I have heard a lot of praise for BitWarden and VaultWarden on here and so probably going to try them out first.

My questions are to those of you who self-host, firstly: why?

And how do you mitigate the risk of your internet going down at home and blocking your access while away?

BitWarden's paid tier is only $10 a year which I'm happy to pay to support a decent service, but im curious about the benefits of the above. I already run syncthing on a pi so adding a password manager wouldn't need any additional hardware.

I don't, specifically because I don't trust myself to host that. I know what people will say here, but I trust 1pass way more than I could do it myself.

1pass uses your password plus a secret key to generate your full "password", meaning you need both to access your vault. The password you memorize, the key you keep safe somewhere (inside the vault is even good, since you probably have it open on another device should you need it). They publish their docs, and show how they encrypt your vaults. To them, your vaults are truly just random bytes they store in blob storage. They don't store your key, they don't store your password, they will not help you out if you lock yourself out. That's the level of security I want for a password vault. If they ever get breached, which hey, it can happen, the most someone will get is a random blob of data, which then I'd go and probably generate a new password and reencrypt everything again anyway.

Vs me hosting myself, I'm sure the code is good - but I don't trust myself to host that data. There's too many points of failure. I could set up encryption wrong, I could expose a bad port, if someone gained access to my network I don't trust that they wouldn't find some way to access my vaults. It's just too likely I have a bad config somewhere that would open everything up. Plus then it's on me to upgrade immediately if there's a zero day, something I'm more likely to miss.

I know, on the selfhosted community this is heresy, but this is the one thing I don't self host, I leave it to true security researchers.
