This is cool Phani, I have an add-on technic for it. Use a fixed number like 4 or 5 along with Horcrux.After the password manager fills the password enter left-arrow 4-5 times (the fixed number that you have in mind) and start entering the Horcrux. You need to remember the number+Horcrux. Some of my colleagues were using it, I felt it super cool. Just incase anyone likes it. 2FA is a must these days BTW.
