The short version
Use one account for daily work and another for administration.
Your normal email account should be used for everyday work. That includes reading messages, opening documents, joining meetings, browsing websites, and communicating with customers.
Administrative work should happen through a separate account that is only used when someone needs to add or remove a user, reset a password, adjust security settings, manage licenses, or make another important system change.
Separating those jobs reduces the chance that an ordinary phishing message or stolen browser session also hands over control of the entire organization.
1. Everyday email accounts face everyday risk
Your regular email account goes everywhere you go. It receives messages from customers, vendors, delivery services, financial institutions, and people you may not know.
It is also used in browsers, mobile devices, cloud applications, document-sharing services, and sign-in pages. Every additional interaction creates another opportunity for a fake login page, malicious attachment, stolen password, or compromised browser session.
Good filtering and security tools reduce that risk, but no system catches everything. An account used this frequently should not automatically have the authority to change the entire organization.
2. An administrator account can change almost everything
An ordinary account usually controls one person’s email and files. An administrator account may be able to reset other users’ passwords, create new accounts, change security policies, alter recovery information, manage licenses, and grant additional access.
That makes an administrator account much more valuable to an attacker.
If a daily email account also has full administrator rights, a successful phishing attack may give the attacker much more than access to one mailbox. It may give them the ability to take over other accounts, weaken protections, create hidden access, or lock the real owner out.
3. Give the owner two separate accounts
A business owner who manages Microsoft 365 or Google Workspace should normally have two accounts.
The first is the everyday account. It has email, files, calendars, and the applications needed for regular work. It should not have broad administrator rights.
The second is a dedicated administrator account. It is used only when management work needs to be done. It often does not need its own mailbox or a full software license.
For example, [email protected] could be used for daily email and regular work, while [email protected] is reserved for approved administrative tasks.
The administrator account should not be used to read ordinary email, browse unrelated websites, or sign into applications that do not require administrative access.
4. Protect the administrator account more carefully
A separate administrator account is useful only if it is properly protected.
It should have a unique password, strong multifactor authentication, and recovery information controlled by the business. A security key or another phishing-resistant sign-in method is preferable when the platform and licensing support it.
The account should not remain signed in all day. Sign in when administrative work is required, complete the task, and sign out afterward.
Using a separate browser profile can also help prevent the daily and administrative accounts from being confused.
5. Do not depend on one person or one account
Separating daily and administrative work solves one problem, but the business still needs more than one controlled path into its systems.
If the only administrator becomes unavailable, loses access, leaves the company, or has an account suspended, the business may be unable to manage its own users and services.
Microsoft and Google both recommend maintaining multiple administrator accounts. These should be separate, identifiable accounts rather than one shared username and password.
A trusted IT provider can also have a named administrator account when the client authorizes it. That makes it possible to assist with password resets, account changes, security settings, and recovery. The provider’s account should never replace the owner’s access or become the only key to the system.
6. Keep ownership with the business
Your technology provider may help administer the environment, but the business should retain ownership and recovery authority.
The owner should know:
- Which accounts have administrative access
- Who controls the domain registration
- Where recovery information is stored
- Who receives billing and security notices
- How access can be recovered if an administrator is unavailable
- How a former employee or former provider would be removed
This prevents key-person risk, where one employee, contractor, or service provider can make or break access to the company’s systems.
The goal is not to give administrator rights to everyone. It is to make sure the business has a small number of properly protected, accountable administrators and is never dependent on only one of them.
7. Review administrator access regularly
Administrator access should not be set once and forgotten.
Review the list periodically and remove access that is no longer needed. Confirm that recovery information is current, multifactor authentication still works, and emergency access has not been lost or disabled.
It is also worth checking recent administrator activity. Separate named accounts make it easier to see who changed a setting, reset a password, or added a user.
A simple review every few months can catch old provider accounts, former employees, unnecessary privileges, and recovery information that no longer belongs to the right person.
