I haven’t had any problems with it, but I wouldn’t store my passwords or bank account numbers in it, unless you encrypt them first.
At the end of the day everything can be hacked including the hard drive in your computer, so it comes down to weighing the risks vs the benefits.
Then you need a password to unencrypt them; I already have more PWs than I can keep track of. Can't go some places because of forgotten/lost passwords.
