authentication in liferay without login hook - authentication

Question

I have a problem, I get the user and password of a view and I check if this data is correct in the data of liferay, when it's correct my method return 1 if the validation is true, but I don't know how to make the successful login in liferay, this is my method:
try {
long companyId = PortalUtil.getDefaultCompanyId();
System.out.println(companyId + " id company");
User user1;
try {
user1 = UserLocalServiceUtil.getUserByEmailAddress(companyId, name);
long cmp = user1.getCompanyId();
Company company = CompanyLocalServiceUtil.getCompany(cmp);
int a = UserLocalServiceUtil.authenticateByUserId(company.getCompanyId(), user.getId(), pass, null,
null, null);
if (a == 1) {
System.out.println("Log in successful");
}
} catch (PortalException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
} catch (Exception e) {
System.out.println("algo salio mal");
}

This seems to be a case where you would need an auto-login hook. In Liferay 7, you just need components like in: https://www.e-systems.tech/blog/-/blogs/autologin-in-liferay-7
You can use an indicator within the user session, like a token, and check it in a custom logic:
#Override
protected String[] doLogin(final HttpServletRequest request, final HttpServletResponse response) throws Exception {
final long companyId = portal.getCompanyId(request);
final HttpSession session = request.getSession();
// code your logic here..
final String[] credentials = new String[3];
credentials[0] = String.valueOf(user.getUserId());
credentials[1] = user.getPassword();
credentials[2] = Boolean.FALSE.toString();
return credentials;
}
This solution is also valid for LR6, the difference is that you are not using OSGi there, so you have to create a hook through the SDK.
