Registration
To use the MySainsburys portal, every employee needs to be registered. You don’t create the account yourself, HR or your manager sets it up when you join. They’ll give you your login details, usually your employee number or NI number with a temporary password. In this guide I’ll explain how MySainsburys registration works, what information you need, and how to get help if you can’t log in.

Benefits of Registering for MySainsburys
Having access to MySainsburys isn’t just about logging in — it makes your work life much easier. Once you’re registered, you can:
- View payslips online – no need to wait for paper copies.
- Check your shifts and rota – handy if you want to plan around work.
- Book holidays and time off – request leave directly through the portal.
- Update your details – keep your contact info up to date so HR can always reach you.
- Stay connected – see company news, policies, and updates in one place.
- Save time – you don’t always need to go to HR for small things.
Personally, I find the biggest benefit is being able to see my payslip before payday. It helps me plan my budget and check everything is correct.
How Do I Register for MySainsburys?
Unlike online shopping accounts, employees don’t create their own accounts from scratch. When you join Sainsbury’s, your manager or HR team sets up your profile and gives you your login details.
You’ll normally receive:
- Username: often your employee number or National Insurance (NI) number.
- Temporary password: this will be given by HR or your line manager.
Once you have these details, visit the official employee login page. Then, sign in for the first time. You’ll then be asked to change your password to something secure and memorable.
When Will I Receive My Login Credentials?
You’ll get your login details once your job contract is processed and your name is added to the payroll system. In most cases, this happens within your first week of employment. If you haven’t received anything after that, ask your manager or HR department.
What Information Do I Need to Register?
For the employee portal, you’ll need:
- Your employee number or NI number.
- The temporary password given by HR.
- Access to the official MySainsburys login page oursainsburys.co.uk.
That’s it. No long forms or extra sign-up is required.
Can I Register Myself Online?
No. Employees cannot self-register. The system is linked to Sainsbury’s HR and payroll, so only HR can create accounts. If you are new and haven’t got your login yet, speak to your manager or payroll team.
Why Can’t I Get Into My Sainsbury’s Account?
From experience, these are the most common reasons:
- Wrong username (double-check if it’s your NI number or employee ID).
- Forgotten password (use the reset option on the login page).
- Account not activated yet (HR may still be setting you up).
- Too many wrong attempts → the account locks. You’ll need HR to unlock it.
How Do I Update My Details on MySainsburys?
You can update some details (like your contact number or address) directly in the portal under My Account. For things like bank details or official documents, you may need to go through HR or payroll.
I always recommend checking your details after your first login, just to make sure everything is correct in the system.
