Fine to put trivial constructor/destructor inline in header file.

Acknowledged. But inlining led to compile time errors.

+
+  // The user's unique account name such as email id.

Should these be static method in an AuthData class instead? Or perhaps in their
own AuthData namespace. Depends on prevailing style (need to ask someone in
Mojo)

+Mitch - thoughts?

+
+// Parses and creates an AuthData instance from a string representation.
+AuthData* GetAuthDataFromString(const std::string& str);
+
+}  // namespace authentication
