This is a security concern. See https://www.mathworks.com/matlabcentral/answers/813140-confusing-warning-during-compilation-warning-matlab-preference-entry-smtp_username-has-been-remo

Thank you very much, the previous error no longer appears. However, there are several interfaces with databases and the buttons do not work or anything at compile time.

The Database Toolbox does not appear to be supported for compilation or code generation.

Notice that https://www.mathworks.com/help/database/ug/database.html there is no "Extended Capabilities" section.

If you have the patience to wait for https://www.mathworks.com/help/referencelist.html?type=function&capability=codegen to finish rendering, notice that the list skips from Computer Vision with Simulink to Deep Learning Toolbox
