In case you don’t remember your password, visit Betfair’s login page and click the “Forgot password” link. After that, put the email address you used when registering for the account. If the email address matches a record in Betfair’s database, they will send you an email bearing a password reset link. Sometimes the email goes to the spam folder. Therefore, if it doesn’t appear in your Inbox folder, check the spam/junk folder.
