What is account separation?

If you act anonymously, you need to separate accounts.

However, simply creating another account is not enough.

Username, email address, phone number, recovery email, icon, profile, follow relationships, and login environment.

If these overlap with the real-name side, the accounts connect.

Account separation means separating the real-name side and the anonymous side in identifiers, environments, and behavior.

A separate account alone is not enough

Even if you create an account under a different name, it is not separated if the registration information is the same.

Registering with the same email address. Using the same phone number. Setting the same recovery email. Logging in from the same browser. Using the same icon.

In these cases, the accounts may look separate on the surface, but they are connected behind the scenes.

In account separation, look at both information visible on the surface and information handed to the service.

An account is not made only of a display name. It is a bundle of registration email, phone number, recovery destination, login device, cookies, payment, contacts, profile, follow relationships, and posting time. Even if the name is different, separation becomes weaker when these overlap with the real-name side.

A common misunderstanding is that a separate account will be treated as a separate person. From the service side, accounts using the same device, same phone number, same recovery email, same IP address, or same browser can look related. From the outside, the same icon, writing style, or relationships can also connect them.

Separate the username

Usernames are searched.

An old handle. The same word as a real-name account. A birthday or favorite number. The same combination of English words.

These lead back to your past self.

Choose an anonymous username that does not overlap with past accounts, real-name accounts, or other services. Search it and check whether your existing information appears.

The longer a username is used, the more it takes on a sense of the person. An old game ID, forum name, social media ID, creative alias, or part of an email address can connect through search. A birthday, region, favorite number, or verbal habit can also be a clue to people who know you.

When creating a name for anonymous use, choose one that does not remind people of your past self. After creating it, search the same string and check whether your past information appears. Also check similar names and spelling variations.

Separate email and phone number

Email addresses and phone numbers are very strong identifiers.

If you use a real-name email address for an anonymous account, separation breaks at that point. A phone number is even stronger, and is also used for identity verification and contact syncing.

Recovery email needs attention too. Even if it is not displayed, the service can connect it internally.

For accounts that need anonymity, separate the registration information itself.

Phone numbers require special care. They are used for identity verification, SMS verification, contact syncing, friend suggestions, and account recovery. If you use the same number on the anonymous side as on the real-name side, the service can strongly connect them internally even if outsiders cannot see it.

Email addresses are the same. Even if you do not use a real-name email for registration, setting it as the recovery email still connects the accounts. When creating an anonymous account, separate the registration destination, recovery destination, and notification destination.

Separate profiles and relationships

A profile reveals the person behind it.

Hobbies. Region. Occupation. School. Community affiliation. Common wording.

If you include the same information as on the real-name side, the value of the anonymous account weakens.

Follow relationships also need attention. If you mostly follow the same friends, workplace contacts, small communities, or regional groups as the real-name side, the candidate set narrows through relationships.

Accounts are seen not only through profiles, but also through relationships.

Follow relationships are stronger clues than many people expect. If the anonymous side follows the same small community, friends, regional groups, or workplace contacts as the real-name side, candidates narrow. Even if you think you are reacting only on the anonymous side, reacting to the same topic, at the same time, and to the same person as the real-name side creates correlation.

Hobbies and expertise in a profile also need care. You do not need to become completely bland, but listing the same words as the real-name profile can connect through search or memory. An anonymous profile should contain only the information needed for its purpose.

Separate the login environment

Even if the accounts are separate, they mix if you use them in the same browser.

Cookies, LocalStorage, browser history, saved passwords, extensions, and device information overlap.

Use anonymous accounts in a browser dedicated to anonymous work. Avoid switching between real-name and anonymous accounts in the same browser.

In high-risk situations, separate not only the browser but also the device or OS.

Switching between multiple accounts in the same browser is convenient, but risky. You may post to the wrong account. You may search for anonymous-activity information from the real-name account. Saved passwords or autofill may make you use a different email address by mistake.

In account separation, separate the environment used after creation too. Prepare a browser, email account, cloud storage, and file location dedicated to anonymous work.

Mixing during operation

Account separation is not only work done when creating the account.

The longer you use it, the more real-name-side habits can mix in.

Reacting to the same topics. Posting in the same time periods. Writing in the same style. Using the same images. Replying only to real-name-side acquaintances.

These behaviors are also material for account correlation.

Maintain separation across the entire operation, not only in registration information.

In long-term operation, personal habits appear. Posting at the same time. Using the same phrasing. Choosing images in the same way. Reacting strongly only to the same people. Reacting to the same news from both the real-name side and the anonymous side.

Account separation is not a wall you build once at the beginning. It is a boundary you keep while using the account. When that boundary breaks, look at the cause and change the operation.

What to check before account creation

Before creating an anonymous account, check the registration information and operation. Some services let you change the email address or phone number later, but the initial registration history or identity-verification information may remain.

Account creation is the entrance to anonymous operation. If you connect it to the real-name side at the entrance, careful post content later will not fully restore separation.

Summary

Account separation means separating the real-name side and the anonymous side in identifiers, environments, and behavior.

Creating a separate account is not enough. You need to separate the username, email address, phone number, recovery email, icon, profile, follow relationships, and login environment.

You also need to avoid too much overlap in post content, timing, writing style, and relationships.

To protect anonymity, see an account not as a “name,” but as a bundle of identifiers and behavior.
