Guys it is very easy to recover your email ID if you have forgotten your password just follow the steps below : -
1) - Enter your email ID and click on forget password.
2) - Then enter the information they are asking.
Which could be another email ID but most probably it will the phone no like 9* 00 which should be with you as they will send an One time password ( OTP) to it.
3) - Thus when you enter the that OTP it will ask for a new passpord and then re-entering it.
And your email and password will be retreived.
To stop this from happening keep same passwords in all the ID’s.
