Not sure if 1Password has it, but I am moving from Keeper, and the only thing I am missing so far is the built-in mechanism to change passwrods.
With Keeper I either:
1 - Get a question from the extension if I was updating the password and if I say yes it automatically changes for me.
2 - Bring the command to change password and it helps me with steps to change the password.
Both of these make it very hard for me to make a mistake. With bitwarden I need to do it manually which can be error prone. But this is the only downside to a lot of upsides like ease of use, lack intrusive ads to buy other products from them, cheaper premium and I prefer the look and feel. Keeper is a bit invasive and in some UIs it gets in the way. Bitwarden doesn’t force that.
