Introduction
Two-factor authentication is necessary, but it shouldn’t become a single point of failure. A common scenario: an advertising dashboard, analytics, a domain, or email are linked to a person’s personal account. As long as that person is reachable, everything is fine. But if the person leaves, loses their phone, or has a conflict with the project, access becomes a business problem.
Symptoms
The symptoms appear suddenly: you can’t log in to the advertising dashboard, you can’t accept an invitation, the code is sent to someone else’s phone, the recovery email doesn’t belong to the account owner, there are no backup codes, and payments and ads continue to be tied to an account that the business doesn’t formally control.
What is being checked
- Who is the owner of each critical service?
- What roles have been assigned to employees and contractors?
- Where are 2FA and backup contacts linked?
- Are there any recovery codes, and where are they stored?
- Is it possible to transfer ownership without losing data?
- Which integrations are linked to my personal account?
- Which access permissions can be replaced with temporary roles?
Correction Process
First, a map of services is created: domain, DNS, hosting, email, advertising, analytics, CRM, telephony, and bots. Next, the owner, administrators, and recovery methods are verified. Personal accounts do not necessarily need to be deleted immediately: first, managed roles and a backup login are created, and then unnecessary permissions are carefully revoked.
Normal result
A good outcome is when the business owner has control over critical accounts, 2FA isn't tied to a single random device, backup codes are saved, and contractors are granted exactly the permissions they need to do their jobs.
Conclusion
2FA should protect a business, not tie it to a single phone. It’s best to get your access permissions in order before you need to log in urgently.
