My first language is Korean. A lot of the time people just write some words or phrases in Korean in English keyboard layout.
If I, for example, write 손톱깎이, that way, which is nail clipper in Korean,
thsxhqRkRdl
Basically totally random. Add in some numbers and !@#$% and you have easy to remember, quick to type and secure password.
Quite nice.
I use Vaultwarden personally. It’s just whag a lot of people do.
