The speed at which you can get a degree can look like a red flag, but you are mistaken about the accreditation. Regional accreditation is actually what you want, not national. Most universities you think of are regionally accredited, whereas the for-profit ones that you can't transfer credit from are nationally accredited. Ie, Stanford = regionally accredited, DeVry = nationally acccredited.
WGU is accredited by NWCCU, which is the same as the University of Utah, University of Washington, etc.. See: https://nwccu.org/member-institutions/directory/
