What to Do If You Suspect Your SMS Account Is Compromised

SMS account security and what steps to take.

Written by Tom Hext

If you’ve received a suspicious email claiming to be from the Home Office (e.g. a password reset, security alert, or urgent SMS action) and you think your SMS account may have been compromised, act immediately. Follow the steps below to protect your sponsor licence.

🔐 Step 1: Secure Your SMS Account Immediately

As soon as possible:

  • Log in to the Sponsor Management System (SMS) directly

  • Always access SMS via www.gov.uk — never through an email link

  • Change your SMS password

  • Use a new, unique password that is not used anywhere else

➡️ If you can’t log in, move straight to Step 3.

🔑 Step 2: Secure Related Accounts

If the same password was used elsewhere:

  • Change passwords for:

    • Email accounts

    • Any shared admin or immigration systems

  • Check whether other Level 1 or Level 2 users may be affected

⚠️ Your email account is especially important, as it can be used to reset SMS access.

🔍 Step 3: Check for Unauthorised Activity in SMS

Review your SMS account for:

  • Changes to Level 1 or Level 2 users

  • Unexpected CoS assignments

  • Changes to organisation details

  • Reports you didn’t submit

❗ If you see anything you don’t recognise, stop and move to Step 4.

🚨 Step 4: Escalate Immediately

  • Inform your internal Sponsor Licence Owner / Authorising Officer

  • Contact Borderless Support as soon as possible

  • If you believe licence misuse has occurred, Borderless can advise on next steps with the Home Office

Time matters - early action can reduce licence risk.

⛔ What Not to Do

  • Do not click further links in suspicious emails

  • Do not reply to the sender

  • Do not share passwords, verification codes, or screenshots containing credentials

🛡️ How to Reduce the Risk Going Forward

  • Treat unexpected SMS password reset emails as suspicious

  • Only access SMS by navigating directly to gov.uk

  • Limit SMS access to essential users only

  • Use strong, unique passwords for SMS and related email accounts

  • Review SMS users regularly

ℹ️ Important to Know

The Home Office will never:

  • Ask you to reset your SMS password via an email link

  • Request login details by email

  • Pressure you using urgent or threatening language

🚩 If an email creates urgency, that’s a red flag.

ℹ️ Borderless Users on Your List Are Expected

Before you escalate a user you do not recognise, check whether it is a member of the Borderless team. Borderless is added to your licence as a Level 1 user so we can carry out sponsorship work for you, and the same name can appear more than once while a request is waiting for a Home Office decision. Borderless users on your SMS account explains what those entries look like and what each status means. If a name is not ours, follow the steps above.
