A: Sorry, that is simply not possible. The current US Government recommendation for strong passwords is a minimum of 15 characters. Our brains would have a tough time remembering just five such passwords, much less a different password for every website.
The easy solution is to use a password manager to automatically create, store, retrieve, and enter these monsters. I’m fond of LastPass. Super easy, automated, integrates with Android, iOS, macOS, Windows, all major browsers, encrypts passwords at the device, shares the password database among all of your devices, and with the for-fee version, you can share designated passwords with family or staff.
