Three Level Password System

As it turned out, according to a study conducted in the UK, every tenth user holds in his memory about 50 passwords. But this encouraging statistics ends. More than 60% of Britons, it turns out, always, everywhere, and everywhere use the same password. (utro.ru)

In my opinion the best use of 3 levels of passwords.
I have been using this system for more than a year now and now I decided to bring it to the people.
I apologize if something similar has already been written by someone ...


')
1. For critical services (payment systems, main mail, ICQ)

Password must be complicated and long
Example: NF $ H * 34gr7d341gT (absolutely random combination of upper and lower case letters, numbers and special characters)

Restoring this password should be tied to what other people do not have access to. When you enter this password or data to recover it, it is worth checking 100 times there if you enter it.

This password you enter in 5% of the services where you are registered

2. For important services (additional mail, registration on important, but not critical for life sites, login to the computer)

The password must be long but not necessarily particularly difficult
Example: vt [fdjq [jkjlbkmybr (this combination means “mech-fridge” in the English layout. In the word “mech”, a mistake was made in the word brute force)

To recover the password is specified primary mail

This password you enter in 20% of the services where you are registered

3. For suspicious and meaningless services (chat rooms, forums, bookmark systems, registration in directories, multimedia portals)

Example: superparol (something that is very easy to remember, what is written on your monitor or keyboard)

Additional mail is indicated for password recovery.

This password you enter in 75% of the services where you are registered

In addition, for ease of remembering, you can use a system of increasing password complexity:
Level 3: ngrdgt
Level 2: nFH34grdgT
Level 1: nF $ H * 34gr7d341gT

In the comments I propose to leave their options for creating a simple password system.
Thank you for taking the time to read ;-)
