How to sign into Apple Account?

Hello estela31,

I clearly see you are asking about how to sign into an Apple Account. I also infer from your being able to post a question to this forum that you already have an account and have signed in to be able to post here.

Read this support article to learn how to sign in with an Apple Account on various kinds of devices --> Sign in to your Apple Account - Apple Support

For an Apple Mobile device:

1. Open the Settings app.

2. Tap Sign in to your [device].

3. Enter your Apple ID and password.

4. If prompted, enter the six-digit verification code sent to your trusted device or phone number and complete sign in.

If another Apple Account is signed in you may need to enter the password for that account to sign out of that account first.
