Autosomal DNA is the DNA we get equally from both parents. Most people have autosomal DNA tested at one of the five major testing companies (23andMe, Ancestry, Family Tree DNA, MyHeritage, or Living DNA). The following are 3rd Party sites and tools.
Note that I try to include only those sites and tools that are actively maintained. This helps ensure the security of the tools. It not a guarantee though. Please only use tools after carefully reading each one's privacy policies.
