Cloud based solutions, regardless of who you go to carry a measure of risk. I use bitwarden and my details are on the cloud but they audit their systems, the software is open source and if push comes to shove, you can self host. I have a measure of confidence. If I host on my own server, is that any safer? Apple's iCloud with their keychain offers a measure of confidence. I also have a measure of confidence with 1Password.
My problem with last pass is that this isn't the first time its happened. They seem to continually downplay the issues, but it keeps happening.
I had no idea you could self-host Bitwarden... Interesting. Been using Bitwarden for a few now and no complaints... knock on wood.
I would be pissed and moving far away from LastPass at this point. This is unacceptable.
