Password overload.

[Anomalocaris]

Which requires password to manage your passwords.

One password to remember vs. hundreds. I'll take that trade-off.

Many of these password managers does the same thing as password managers in Apple, android, or windows OS, except to create an intimidating but false air of greatly increased security,  many password managers apps make it essentially impossible to recover the one password, or to change it, if you by chance forget it.    

So if you forget your one password on these password management apps, you permanently lose access to all passwords stored behind it unless you wrote them down somewhere else.
