Password manager is as important as you keep the password of your mobile. I mean you can not just put the random password of your online account and keep it free hand.
And it gets more of a tiring job when we have either not registered our contact number to receive an OTP or when we have no longer access to our old email address.
Adding to this, we are also aware that in these days we have online accounts we cannot even keep a record of that is for everything, and are so important. We online accounts to cover our banking sector, college, online classes, medical, insurance, etc, and so much more.
