A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Ask the fire service’s Microsoft 365 IT administrator to require MFA re-registration for your fire-service account, because changing its password does not reset the blocked Authenticator registration.
What to ask the fire service for
Contact the fire service IT help desk again and send or read them this exact message:
I can sign in with the password you supplied, but I cannot complete Microsoft Authenticator verification. Please ask your Microsoft 365 Authentication Administrator to select Require re-register MFA for my account. I need help registering Authenticator again afterward.
This is different from requesting another password.
Their Microsoft 365 administrator should:
- Sign in to the Microsoft Entra admin center.
- Open Entra ID → Users.
- Select your fire-service account.
- Select Authentication methods.
- Select Require re-register MFA.
- Confirm the action.
That removes the unusable Authenticator registration and prompts you to register a new verification method at your next sign-in. The administrator needs at least the Authentication Administrator role to perform it.^1^
Because repeated attempts have already resulted in blocking, do not continue entering codes. Microsoft advises contacting the organization’s help desk after repeated attempts when the available verification method still does not work.^2^
After IT completes the reset, ask someone from the fire service help desk or your carer to stay with you while you sign in and register the phone again. Also ask whether they permit a second backup method, such as a telephone call, text message, or another approved option.
Paying your Microsoft bill
Your fire-service mailbox and your personal Microsoft subscription may be two separate accounts. The fire service controls access to its work account; Microsoft customer support handles a personal subscription and billing.
For personal billing help:
- Open Microsoft’s customer-support page.^3^
- Select the option for a Personal account or Microsoft technical support.
- Choose Get Help.
- Enter:
“I cannot sign in to renew my Microsoft 365 subscription and need account and billing assistance.” - If offered, choose Contact Support, chat, or the telephone option for the United Kingdom.
Support can help route the billing issue, although agents are not permitted to bypass account security or directly change account details. Subscription-renewal guidance also directs users who cannot sign in to the sign-in helper and then Contact Support.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Problems renewing a Microsoft 365 subscription")
Protect your personal information now
Your message contains personal telephone numbers and identifying information. Edit or delete those details from the public post immediately. Do not post passwords, Authenticator codes, account numbers, or verification codes. Microsoft staff should never ask for your password or an Authenticator approval code over a public forum.
This forum cannot telephone you, access the account, or schedule a callback. The two appropriate human-support routes are:
- Fire-service IT help desk: reset MFA for the fire email.
- Microsoft customer support: personal subscription and payment assistance.
