On a more philosophical note, I think we are rapidly approaching the end of the password whether we like it or not. My phone has facial recognition, my laptop has a fingerprint scanner. Most services on both mobile and desktop stay logged in for months or even years at a time, or leverage one of those hardware-biometric options to renew their logins.

As a result, by the time I have to type in one of these passwords, there's no hope that I remember which of the 50-100 passwords a particular service correlates to. I could use one password for everything, but that's insecure. I do use LastPass, but that's basically an inconvenient stopgap for some concept of "universal login" (it's especially painful on mobile, where I either use Lastpass's own crippled web browser, or badly copy/paste credentials).

In so far as I can, I approximate universal login by delegating logins to widespread platforms. Mobile apps mostly just use Apple's concept of identity. Games use Steam/Blizzard/Origin/XBox. Most online sites that support federated login, I tie to one of Google/Facebook/Twitter.

I long for the day when we see sufficient consolidation of authentication that I can federate everything through a single set of password+2fac, that is indefinitely sticky on my personal devices.

Now we have apps to manage passwords that needs a password

Yes, but it's a single password. Which is not that different from having a single ID card/driver's license.

Btw: You should make that single password a "correct horse battery staple" so you can remember it and it's very hard to crack.

(The number of words and such that you want to include varies by your assumptions about strength and attacks.)
