I experimented with Bitwarden for a little while, but it didn't have a good method for changing passwords. I ended up switching back to LastPass. But, I'm pretty frustrated with their buggy iOS app.
Can you elaborate? Changing a password with Bitwarden is just editing the field or–even better–a one-click button to (re)generate a new random password (including options for length and complexity requirements). If you are logged into the browser addon, it will also (depending how javascript-hacky the website is) prompt to save the new password when you modify the password in a website's settings.
Unless you're talking about mass-replacing a single password across a bunch of different entries? Which is certainly not a limitation of any password manager; reusing a password is just horrible.
Lastpass has a feature called auto password change [0] that allows you to update a password directly from inside lastpass at the click of the button. It doesn't work for all sites but it's a pretty nice feature.
I haven't had that problem with BitWarden in testing, but I can't change to BW until they come up with some solution for having both a work and and personal vault. The ability to link-in your personal LastPass to your work LP without actually giving your employer any access to your personal LP is really beneficial to my staff.
I'm actually using BitWarden for work and personal stuff and it works wonderfully. BW allows you to "link" the two accounts and share things between them (or not). For example, my personal Gmail account information is in BW but its not exposed to my employer at all. On the flip side, I've created management accounts (ie. JIRA admin user) and shared them with the "IT" team in BitWarden; this allows all of the IT admins to get into JIRA if necessary.
