Creating a strong password that you'll remember can be a pain, especially when you're using a dozen different passwords for everything from your bank to your Instagram account. Here's a tip from Ed Bott on how to set up a personal identification number that can make logging into your computer a little faster.
To set up your PIN, go to settings and click Accounts. Then select Sign-in Options. The PIN option will be there.
You'll be asked for your password first. Then enter your new PIN.
The default option for a PIN is four digits, but you can use a longer one. Remember not to use anything someone might easily guess, like your birthday.
Once you've created a PIN, you can always switch back to using a password by clicking the Sign-On options button on the screen where you enter your credentials.
