some coffee apps will be malicious now with 'melange' as IoC haha.. and Navigator xD... but i guess netscape is kinda malware o.O.
on a more serious note. i told you so levels reaching new heights. dont use password managers. dont handoff this type of risk to a third party.
its like putting all your keys in a flimsy lockbox outside of your appartment. at some point someone will trip over it, find the keys and explore -_-.
it being impractical with the amount of keys/passwords you need to juggle?
not an excuse. problem should and can be solved differently.
