I noticed on the Microsoft Privacy & Safety Site, a step-by-step (easy) method for creating complex passwords. I started using this method and now find myself using it all of the time. I suggest you bookmark or print out this method. It may look like there is a lot to it; however, it actually is quite easy to do.
Step 1: Start with a sentence or two (about 10 words total). Think of something meaningful to you.
Example: My cat is named Bucket. She is a fat cat.
Step 2: Turn your sentences into a row of letters. Use the first letter of each word.
Step 3: Add complexity. Make only the letters in the first half of the alphabet uppercase.
Step 4: Add length with numbers. Put two numbers that are meaningful to you between the two sentences.
Step 5: Add length with punctuation. Put a punctuation mark at the beginning.
Step 6: Add length with symbols. Put a symbol at the end.
Now test the strength of your Password [HERE] at the Microsoft Safety & Security site.
