Currently there is no online link to retrieve Lycamobile password. Alternatively call 322 from a Lycamobile or 02071320322 from other phones to speak with an agent of Lycamobile. They will ask you couple of security questions and they will send the password to both your registered email and mobile number shortly afterwards.
