MySudo — summary
MySudo is a useful compartmentalization product (one app, many disposable numbers and emails) but it is not no-KYC — Apple/Google billing binds the user.
- + Polished UX for managing multiple identities (numbers, emails, payment cards) from one app.
- − Operator binds payment via Apple/Google billing; you are very much identified.
- − The "Sudo" identity model is about compartmentalization within services *to other parties*, not anonymity from MySudo itself.
- − Not appropriate when the threat model includes a U.S. operator with subpoena reachability.
OtpFactory — summary
OtpFactory is a number-leasing service tuned for receiving SMS to validate accounts on phone-gated services — Gmail, Telegram, Signal, marketplaces, exchanges.
- + 50+ country pool for receiving SMS — useful for validating Gmail, Telegram, Signal and other phone-gated accounts.
- + Long-term number rentals available, not only one-shot SMS reception.
- + Bundles ready-made Telegram, Signal and similar account creation alongside number rental.
- − Numbers are shared / VOIP-style; some banks and high-trust services reject the carrier.
- − Number-pool availability shifts per country and per provider; popular SKUs run dry.
