I’m with you on this. I tried every popular option a few years ago and found all of them to be rather atrocious, but settled on self-hosting VW, and found its mobile integration (using BW clients/apps) to be as close to native as anything, and its 2FA (for TOTP anyway) is superb. Nothing else thus far allows me to launch a website or app and login with 2FA faster than Bitwarden. I operate under the assumption that everything has a weak spot, at least Vaultwarden isn’t hiding the source code and if BW’s VC backers dictate some kind of rule-breaking change to the service, it won’t affect my data and forks/OSS alternatives will be easily readied to interface with it.
