Windows 10: A question about passwords

Me, again so soon, a different question but brought to my attention by members who answered my last thread on W10 clean install.

Passwords
Correct me if I am wrong, but we are supposed to have a password for every site we use. We are not supposed to write those passwords down anywhere, well I don't know anyone who could remember say 20 different passwords.

With this in mind, I was taught on a previous site (IDF50) (I don't feel 50) that to overcome the above problem was to think or create a phrase that's easy to remember for example " the best pc forum for help is w10" and you take the first letter of every word Tbpffhiw10 so you have the capital and number normally required.

BUT, after stating all above, it was pointed out to me the benefit of lastpass or others.

my question is, how safe is it, as we are placing our 20 different passwords in their vault ??

admin password?

You can reset the Admin Password using Windows XP repair; See Here for step by step.

Admin password unknown and missing files after upload


Ok, I know these questions have been asked, but I have tried everything I can understand.
Need to be spoken like a noob - step by step please.
Win10 put on my system everything initially fine, then discovered files missing - tried to install a recover program to be frustrated by a prompt to input an admin password with User [USER-PC\USER]
I have tried every password ever used.
I have tried going to cmd prompt
I cant install anything to circumnavigate because I cant get past this dialogue.

any suggests?

 

Password issue

After going through the steps to make a new password, after a week or two, my login credentials are no longer valid. I'm forced to make a new password all over again. It seems to happen if I don't login in a certain period of time. Does our passwords expire???
