Self-hosted projects are rarely limited to a single server. To run them, you often need to create accounts with hosting providers, cloud platforms, domain registrars, and other services where SMS verification may be required during registration or login.
A personal phone number is usually not used for such purposes, as few people want to mix their work infrastructure with their personal data. It is much easier to separate work accounts from personal information from the outset and use a separate number for them. Depending on the task, this can be a permanent virtual number or a temporary phone number service for short-term projects and test accounts.
In this article, we'll look at how to work with SMS confirmation in self-hosted projects without exposing your personal number, and which options are best suited for different use cases.
Why use a separate number for work accounts?
When choosing between using a personal number or a separate one for work accounts, it is important to understand that in a self-hosted infrastructure, a phone number can be used more than once when creating an account. You may need it to verify your identity again, restore access, or receive notifications about account activity. Therefore, when choosing a number, it is important to take into account not only whether it can receive the initial SMS, but also how long you will need access to it.
In addition, a separate number provides access control benefits. If the number belongs to a single administrator, receiving an SMS may depend on that person's availability. When transferring the project to another specialist, you will have to separately address access to the number and associated accounts.
You also need to understand that if a project has several providers, registrars, and cloud platforms, it is more convenient to determine in advance which accounts require a permanent number, and which can use a limited-term solution. Planning the purpose of the number and considering possible future uses in advance can help reduce costs and prevent problems with account recovery. For such purposes, a temporary or virtual number is used as an additional number.
Temporary and virtual numbers: what is the difference?
Temporary and virtual numbers serve different purposes. A temporary number is usually used for a short period of time, when the number is needed only for setting up or testing a project. After that, there is little reason to keep it.
The situation is different with a virtual number. You can retain it and use it later, for example, if the service requests confirmation again or you need to recover your account. Therefore, this option is usually more convenient for the primary work accounts.
When choosing, it is worth looking not only at the rental period. Some services do not accept certain types of virtual numbers, and temporary numbers may not guarantee future access. This is a critical consideration for important accounts: losing access to a number can make account recovery difficult.
Therefore, it all comes down to the purpose of the account. For a temporary environment or a test project, a short-term solution is sufficient, and for infrastructure that is intended for long-term use, it is better to choose a number with long-term access.
How to protect accounts after SMS confirmation
SMS verification solves only one part of the problem — confirming the phone number when registering or logging in. After that, the account still needs to be properly protected, especially if it can be used to manage a server, domain, or other project resources.
You should start with a unique password and restrict access to the account itself. If the service supports two-factor authentication through an authenticator app or a hardware security key, it makes sense to enable it in addition to SMS.
This is especially important for CyberPanel administrators. The panel is used to manage server infrastructure, so it is better to consider additional account-protection measures alongside the overall security configuration.
You should also check the available account-recovery methods. The phone number, email address, and recovery codes should remain accessible to the people responsible for the project, but they should not be stored in plain text along with passwords.
Final Thoughts
Phone verification remains a common part of registering and securing accounts used in self-hosted projects. However, there is no need to provide a personal number every time, especially when it comes to production servers, domains, and cloud services.
A separate virtual or temporary number allows you to solve this problem without mixing personal and work data. The main thing is to choose an option based on how long the account will be needed and whether the service may require phone verification again in the future.
Overall, the approach is quite simple: for temporary tasks, use a number for a limited period; for permanent accounts, use a number with long-term access, and treat SMS verification as just one element of a broader account-security strategy.
