Most passwords these days must be at least 8 digits, including capitals, lower, number and a symbol.
Think of a PIN, 4 or 6 up to you. Follow that with a symbol, * / ? or anything YOU want. That's the start of all your passwords. Then use, for example, the last four letters of the 'company' eg Soft for Microsoft, Ogle for Google, Wide for Nationwide etc etc whatever YOU want. Or use all the vowels in the name, or the consonants. All you need to remember is the PIN & symbol, and to start, or end, the letters with a capital.
Or start with the letters followed by the PIN. Easy.
