### Answer
Based on the available information, there isn't a self-service option in the Retell AI UI to change or remove 2FA settings yourself. Here's what you can do:
To change or remove your 2FA phone number:
- Send a support ticket to
support@retellai.com requesting the change [(1) ](
)
- You should receive a reply within 3-5 days
Alternative login method:
- If you need to log in without the phone code, you can click "Try another method" to receive the OTP via email instead [(2) ](
)
Note that 2FA cannot be completely disabled for security purposes .
