How to sign in
You'll need a username and password to sign into the My O2 app.
If you've used My O2 on our website, the same username and password will also get you into the app.
If you've forgotten your password, or need to register, go to our My O2 sign in page.
When you sign in to the app for the first time you’ll be asked to set up a memorable pin. If available, you’ll then be given the option to use fingerprint recognition. This will make it quicker and more secure for you to sign in.
For help and support downloading and signing in to the My O2 app visit our help pages.
