If you don't want your password to have to be entered every time you turn on your Mac, turn on automatic login by following the directions below.
1. Open the System Preferences application.
2. Select Security and Privacy.
3. Select the FileVault tab.
4. Click the Lock in the bottom lefthand corner to allow changes.
5. You should see a button in the FileVault preferences. If the button reads "Turn On FileVault...", skip to step 7.
6. If the button reads "Turn Off FileVault...", click it, and then follow the on-screen prompt.
7. After FileVault is disabled, select the Back button in the top lefthand corner of the System Preferences window.
8. Select Users & Groups.
9. Select the Login Options button at the bottom of the Users list.
10. Select the Lock icon in the bottom lefthand corner to allow changes.
11. Select the drop-down list next to the label "Automatic login:".
12. Select your account from the list.
13. Enter your password when asked to enable automatic login.
Now you will not be prompted for a password when starting up your Mac, and you will automatically be logged in to your user account when your Mac boots up.
I hope you found this information helpful.
