I use a KeePassXC database on a syncthing share and haven't had any issues. You get synchronization and offline access, and even if there are sync conflicts, the app can merge the two files.

One benefit to hosted password vaults over files is that they can use 2FA - you can't exactly do TOTP with a static file.

(As an aside, I wish more "self hosted" apps were instead "local file and sync friendly" apps instead, exactly because of offline access)

Firefox has a built in password manager, it is stored on each machine you sync. But to anwer your question any cloud stored data is vulnerable, so be sure your password manager supports other verification measures such as Yubikey as another factor of authentication

If a FOSS project provides easy self hosting but also a paid hosting I usually go for that to support the project and gain something at the same time. Not only for password managers but any service.

Regarding benefits for the paid tier (which I use as a sort of donation):

1. it's literally on their page: https://bitwarden.com/help/password-manager-plans/#compare-personal-plans
2. What I actually use: A bit of the encrypted upload, some 2FA generators for unimportant services (I prefer using another 2FA app with encrypted automated backups. Helps keeping things separate)

Regarding self-hosting:
I decided against it.

1. Too much important stuff in there (+400 accounts)
2. Too much stuff in there I would need to back up and keep safe. Not in the mood.
3. Not enough experience with hosting a database. If it would go belly-up I had no one except the internet to ask and figure it out myself. At best some selfhost forum/community.

I switched from Lastpass to 1Pass and it was pretty miserable. I then swtiched to Bitwarden. It's not perfect, but it's better than LP and 1Pass.

The reason you'd want to self-host is so that nobody has access to your data but you. "The cloud" is just someone elses computer"

Keepass hosted on my Nextcloud server. You can have the database synced to however many devices you want, and each one will always have a local copy of the latest version. You can use whatever sync solution you want though: syncthing, Dropbox, google drive etc. I suggest using diceware to generate a strong master passphrase for the database :)

I selfhost vault warden, and in all honesty, it's just painless. I do reverse proxy it, but you could also just setup wireguard or Tailscale at home and keep it even more secure that way.

The reason I chose to selfhost is because I want to be in as much control as possible of my data. I chose Vault warden because it's fully featured and super easy to deploy the server, ridiculously so.

Now,if anyone was to ask me if they should selfhost Bitwarden or just use their hosted service, I'd suggest to take the second option, for 2 reasons:

1.- it's even easier and just works 2.- if you choose the paid tier it has some nice features and you help the project stay alive

I don’t understand it tbh. Password managers and email are the main things I avoid self hosting. Email because it’s just too easy to fuck something up and never realize you’re not actually properly sending/receiving email. And password managers because if I lose access to it, I’m kinda royally fucked. And the password managers I use keeps a local copy of your database that gets periodically updated, so even without internet I do still have access.

I use KeepassXC

I've used cloud based services for password managers for work and "self host" my personal stuff. I barely consider it self hosting since I use Keepass and on every machine it's configured to keep a local cached copy of the database but primarily to pull from the database file on my in-home NAS.

Two issues I've had:

Logging into an account on a device currently not on my home network is brutal. I often resort to simply viewing the needed password and painstakingly type it in (and I run with loooooong passwords)

If I add or change a password on a desktop and don't sync my phone before I leave, I get locked out of accounts. Two years rocking this setup it's happened three times, twice I just said meh I don't really need to do this now, a third time I went through account recovery and set a new password from my phone.

Minor complaint:

Sometimes Keepass2Android gets stuck trying to open the remote database and I have to let it sit and timeout (5 minutes!!!) which gets really annoying but happens very infrequently which is why I say just minor complaint

All in all, I find the inconvenience of doing the personal setup so low that to me even a $10 annual subscription is not worth it

I self-Host Vaultwarden at home, this way I have a convenient password manager for myself and my SO, it's easy to setup and maintain. East to access from the phone, Firefox, etc. Bitwarden app keeps a local cache so even when disconnected from the server I have access to my passwords and it will synchronize at the next connections. I otherwise have a Wireguard VPN setup in case I need to connect to my home server from outside my home.

Before I used KeePass+syncthing but it was to much configuration to convince my SO to use it. Bitwarden/Vaultwarden was more successful in that regard.

You'll learn pretty quickly that a large chunk of self-hosting people are the types that are just terrified of having things be outside their control, which by extension means they are terrified of other people that aren't them running infrastructure. 🫠
