Summary

Traditional TOTP (Time-based One-Time Passwords) which relies on symmetric and with or not used asymetric primitive cryptographic keys like FIDO can be vulnerable to interception, bypass, or even QC can finding corrected ECC RSA ECDLP private key from public key such like;

• Computes $$d$$ given $$y$$ = $$x^d$$ mod $$p$$ → ECC/DH Dead
• Computes $$k$$ given $$Q$$ = $$k⋅P$$ → ECDLP Dead
• Computes $$p$$ given $$n$$ = $$pq$$ → RSA Dead
