Oh yeah any small steps you can take to secure your account is always a bonus. Unique password with words, numbers and characters can still be very vulnerable. I would always recommend to use two factor authentication when available.
How strong your pass is not so important if you enable 2fa security feature in your account because it will protect from the hackers to login into your account. The main reason for these things to happen is people use the same combination of email and pass to many sites to remember easily. Need to learn from these mistakes.
True, I have known someone from way back 2015, one of the site he is registered with was hacked and alas all the password of his account in different sites were the same, and he does not have 2fa enabled in an exchange site, no matter how strong the password is if he database was hacked, loging in with your account is just a walkl in the park unless we have this second layer protection such as IP detection on an email account and 2fa. These two is a must for better security.
