I know this a a joke, but please use a password manager, it is such a game changer.
Bitwarden is free and E2E encrypted and if you want additonal feature, they only cost 10 bucks pre year. You can even use it with anonaddy to hide your email, which is also totally free and open source.
2FA one time code was the reason I got premium (and obviously support FOSS project). It is a slight security downgrade, but a whole lot of QOL upgrade.
I also imagine hardware key support like yubikey would be very appealing for many.
