When I'm logging in to Instagram, it is showing ADD PHONE NUMBER TO GET BACK INTO INSTAGRAM

Is there any way I can log in again without any number? To be noted I was already logged in when this message showed up & now, I can’t. T_T

No, there’s no other way. You need to phone verify your account. Did you have to solve a captcha as well? You should use a real phone number to verify the account.

you must add the phone number to verify the account but after login you can remove that phone number easy.
