# A four digit long password [closed]

Mary has a password-protected smartphone, but she is not very good at remembering numbers. She decided to come up with a simple mnemonic, "My favorite things are MILK and EGGS."

Her password is 4-digits long. What is it?

$$9902$$
Check on the phone's number pad, MILK and EGGS represent $$6455$$ & $$3447$$ respectively.
And she likes the both, so add them up, and answer is $$9902$$.
