I've forgotten my username or password (or both)

If you are experiencing difficulties signing into your account this maybe due to the username or password you are using. 

The username you need to view your bill is the one that was set up at the point of sale when your account was initially created. If you purchased your order online you’ll find these details on the email we sent you confirming your order. 

Your username is the first part of your O2 email address. For example, if your email address is 'john.smith@o2.co.uk' your username is 'john.smith'. 

Don't worry if you have forgotten either your username or password as these can be easily reset online.
