MySainsburys Password Reset: Complete Guide for Sainsbury’s Employees

MySainsburys (now officially rebranded as OurSainsburys at oursainsburys.co.uk) is the employee self-service portal used by every Sainsbury’s colleague across the UK. Resetting your password is the fastest way to restore access to your payslips, rota, holiday balance, and HR documents.

This guide covers the full password reset process, the portal’s password policy, common login fixes, how to update your details, and what Kronos (UKG) is — so you can manage your account without calling HR every time.

How to Reset Your MySainsburys Password (5 Steps)

To reset your MySainsburys password, go to oursainsburys.co.uk and click “Can’t access your account?” on the Microsoft sign-in screen. Follow the 5 steps below.

• Step 1: Open a browser on any device (phone, tablet, or laptop) and go to oursainsburys.co.uk. This redirects to a Microsoft-branded sign-in page.
• Step 2: Below the login box, click the link labelled “Can’t access your account?” or “Forgotten your password?”.
• Step 3: Choose Work account as the account type. Enter your Sainsbury’s registered work email address and complete the CAPTCHA if shown.
• Step 4: A verification code is sent to your registered email or phone number. Enter the code immediately — reset links expire within a few minutes.
• Step 5: Choose a new password that meets the Sainsbury’s security requirements (see password policy section below). Log out of all devices after resetting, then sign in fresh.

Pro tip: If your new password is not accepted right after reset, make it longer and more complex. The portal does not always display clear error messages when a password fails the minimum length requirement.

What Is the MySainsburys Password Policy?

The Sainsbury’s password policy follows standard Microsoft Azure Active Directory rules. Your new password must meet 4 requirements:

1. Minimum 8 characters — most employees report 10–12 characters works best
2. At least 1 uppercase letter (e.g., A–Z)
3. At least 1 lowercase letter (e.g., a–z)
4. At least 1 number and 1 special character (e.g., @, #, !)

The portal does not always display a clear validation message when a password fails these rules. If your password is rejected silently, make it longer (14+ characters) with a mix of all 4 character types.

Avoid reusing old passwords — the system blocks recently used passwords. Use a password manager to store your credentials securely.

MySainsburys Login Not Working? 6 Common Fixes

Most MySainsburys login problems fall into 6 categories. Work through each fix in order before contacting IT.

1. Wrong Password or Caps Lock On

Double-check your password and confirm Caps Lock is off. If you have tried the wrong password 5 times, your account locks automatically. Wait 15–30 minutes before trying again.

2. Account Locked After Failed Attempts

Your account locks after 5 failed login attempts. Either wait 30 minutes for it to unlock automatically, or call the IT Service Desk on 0345 603 2282 (press option 2) for an immediate reset.

3. Login Loop — Keeps Redirecting Back to Sign-In

A login loop is usually caused by old session tokens stuck in your browser cache. The fix: open an incognito (private) browser window, log in there successfully, then clear cookies in your main browser and try again.

4. Browser Compatibility Issues

The portal works best on Chrome, Microsoft Edge, Safari, and Firefox. If you are using an older browser or browser version, update it. Alternatively, try a completely different browser.

5. Portal Slow or Down — Peak Times

Login issues are most common on Monday mornings and on pay day, when thousands of colleagues access the portal simultaneously. If the site is sluggish or returning errors, wait 1–2 hours and try again. It is a server load issue, not an account problem.

6. Correct Password But Still Can’t Log In

If your password is correct but login still fails: your account may not be fully activated (common for new starters — activation takes 1–3 working days), or your MFA (multi-factor authentication) details need updating. Contact your line manager or HR.

Issue	Cause	Fix
Wrong password / Caps Lock	Typo or keyboard setting	Check credentials, toggle Caps Lock
Account locked	5+ failed attempts	Wait 30 min or call IT: 0345 603 2282
Login loop	Old session tokens in cache	Use incognito, then clear cookies
Page won’t load	Browser or cache issue	Switch browser or clear cache
Portal slow/error	Peak traffic (Mondays, pay day)	Wait 1–2 hours and retry
Password not accepted	Doesn’t meet policy	Use 14+ chars with uppercase, number, symbol

How to Update Your Details on MySainsburys

Updating personal details (phone number, email, emergency contact, address) takes 3 steps after logging in.

• Step 1: Use your work email and password on the Microsoft sign-in screen.
• Step 2: Click on your name or the profile icon. Select My Profile or Account Settings from the menu.
• Step 3: Update your phone number, email, or address. Click Save or Update My Profile to confirm.

Important: Bank details and payroll information cannot be updated through the portal directly. Contact the Colleague Support Centre on 0800 707 6242 or speak to your store HR manager for payroll changes.

What Is Kronos Sainsbury’s (UKG)?

Kronos Sainsbury’s refers to the workforce management system integrated into the MySainsburys/OurSainsburys portal. It is now officially called UKG Workforce Central (UKG stands for Ultimate Kronos Group). Sainsbury’s colleagues still call it “Kronos” informally.

Kronos/UKG is used for 5 main workforce tasks:

1. View weekly rota and shift schedule
2. Track hours worked and attendance
3. Request and approve time off
4. Swap shifts with colleagues
5. Monitor holiday balance

You do not need a separate Kronos login. Access Kronos directly through oursainsburys.co.uk using your standard work email and password. After logging in, look for “Kronos”, “My Schedule”, or “UKG” on your dashboard. Some stores also use the UKG Workforce Central mobile app (formerly Kronos Mobile) available on Android and iOS.

Server address note: Colleagues have reported the direct Kronos URL as sainsburys.kronos.net/wfc for some store setups. However, this varies by region and rollout. Always use your store’s official link provided during onboarding.

MySainsburys vs OurSainsburys: Old and New Portal Explained

The portal has used 2 names since it launched. MySainsburys was the original name employees knew from initial onboarding. Sainsbury’s later rebranded it to OurSainsburys — the change emphasised team identity over individual ownership. Both names refer to the same platform at oursainsburys.co.uk.

New employees sometimes search for “MySainsburys login” because that is the name they heard during onboarding. Existing employees continue using the term out of habit. The functionality — payslips, rota, holidays, HR documents — remains identical under both names.
