No. AWS MFA relies on knowing a unique secret associated with your hardware MFA (Thales) device in order to support its use. Because of security constraints that mandate such secrets never be shared between multiple parties, AWS MFA cannot support the use of your existing Thales device. Only a compatible hardware MFA device purchased from Thales can be used with AWS MFA. You can re-use an existing U2F security key with AWS MFA, as U2F security keys do not share any secrets between multiple parties.
