I moved to Bitwarden about a year ago when I got fed up with the terrible UI in Lastpass. Bitwarden isn't the pinnacle of UI either, but at least it's way cheaper. Been very happy with it.
So many people recommend Bitwarden now. I am a paying customer from the first day and have been using it on all my devices. Bitwarden followed my Lastpass experience, similar to what OP has described.
Now, Bitwarden's popularity is troubling me. It has become already large enough to be an attractive target for attacks. The bigger it gets, the more lucrative it is for attackers. Similar to the Windows vs. OSX discussions 10 years ago: viruses spread on Windows, because it was big.
Hence, I am starting to worry about using it and asking myself what "the next" Bitwarden is.
What do you think? Is my reasoning going into the right direction? Do you see the point reached where Bitwarden has reached critical mass? What would you recommend as "the next" Bitwarden?
Your thinking about Bitwarden becoming a more valuable target is probably directionally correct, but at least anecdotally, I think the biggest target in this space is going to remain either the built-in Chrome/iOS password managers, or Dashlane, which is a product that advertises widely on Podcasts, etc.
The passwords and all data are encrypted on the client side and the server has no way to decode your passwords so even if Bitwarden's password was stolen, the passwords within the accounts are as secure as the Master password you chose.
Also the fact that the server side is fully open-source (and not just the client) means you could switch to using your own servers at any time.
virus' spread a lot more on windows because of MS's shit stance on security. It an even more popular OS now but the virus landscape is a hell of a lot more limited because they started to take security more seriously. They still have a way to go.
edit: One note about something that was bugging me for a while...items created on my computer sometimes wouldn't show up in the vault for immediate use. Painful when you sign up for a service using your computer and then try to immediately sign into it on your phone.
In the iOS app settings there is 'Swipe down to refresh' (or similar) - turn that ON. Not sure why it was off by default, but it totally fixes the issue. Just swipe down to refresh the vault and your new item appears.
Having a push feature only works if you can engineer your app or add-in to open up the necessary ports or tunnels in the OS itself. Polling on the client end will always be easier to implement.
Also: just checked BitWarden v2.8.0 (449) on iOS 14.4, no setting for “swipe to refresh” anywhere in its settings.
Settings -> Manage -> Sync -> Enable sync on refresh
My trouble was specifically related to the 'Pull down to refresh' behavior being disabled by default though. If that feature is disabled the new items will appear sometime, with no way of knowing when that will be. I honestly don't even know why that feature has an ON/OFF switch, it should just be permanently enabled.
