Access your information with HMRC online or via HMRC's mobile app.

request coding changes
notify HMRC of any new address

track your National Insurance Record
track your State Pension entitlement
and more...
You will need to prove your ID. You will need a) your National Insurance Number and two of tje following 1) current passport 2) current driving licence, or 3) a recent payslip or P60. Two of these are the easiest way to get through ID verification during the setup process.
IMPORTANT TIP: MAKE A NOTE OF YOUR GOV.UK GATEWAY ID and password. Make sure you access the Gateway at least once a year to ensure HMRC don't delete it. Check your income record, PAYE coding notice, State Pension entitlement etc.
