More reason to use password manager.
I would prefer to read “Why unique passwords matter more than ever”. Most online services have rate limits established, e.g. you only have a few tries on your password before google blocks further login attempts.
But if you use the same (or very slightly altered) password for many services, there is a real risk that one of the services gets hacked, your password leaked and attackers use this against your other services.
But of course, the suggestions in the article (password manager + MFA) are still valid and useful.
I would prefer, why 2fa everywhere is important. But not SMS!
If you have 2fa on accounts, your password is only 1 bit of the login. Passkeys or yubikeys will stop most login attempts dead, you can’t send them to anyone.
But yes unique passwords also help, as that 1 service is the only thing with that password.
