Does my German wife have to change her last name on her passport to get into Germany?

Question

She has a German issued passport.

Answer 1

No. She should be able to enter Germany on her German passport as it was issued.

There's no reason for any passport to need to be altered these days, since security is so tight. They'll be able to pull up her records regardless of her name.

Answer 2

If this is a recent marriage, she should bring along her marriage certificate when traveling. Once in Germany, she will need to get a new passport issued in her married name.

Answer 3

change the last name ? not necessary.
she still can use her family lastname instead
