Is it possible to delete the admin user from the user table on MikroTik?

The reason the assertion that the admin user cannot be deleted is correct lies in the fundamental design of the MikroTik RouterOS system. The admin user is a built-in account created by the system to ensure that there is always at least one user with full administrative privileges to manage the router. This design is crucial for maintaining control and preventing situations where a device may be left inaccessible due to the accidental removal of all administrative access.

In MikroTik, while it is possible to manage user accounts extensively — including creating new users, changing passwords, and even disabling accounts — the admin user serves as a safeguard. This ensures that network administrators do not lock themselves out of their equipment inadvertently.

Other options could suggest alternatives to dealing with the admin account, such as disabling it or relaying on a secondary admin. However, even in cases where there may be additional administrative users, the original admin account remains intact and active. Thus, this protective measure is a built-in feature of the RouterOS that encompasses both security and management protocols essential for network stability.
