MySudo

MySudo is a privacy application that lets you create multiple virtual identities — called "Sudos" — each with its own phone number, email address, and private browser. Instead of giving your real phone number and email to every service, store, and contact, you create a Sudo for each context: one for shopping, one for medical, one for financial, one for travel. Each Sudo is a fully functional identity with a working phone number that can make calls, send texts, and receive verifications, plus an email address that can send and receive messages.

For crisis privacy, MySudo's compartmentalization is its superpower. If one identity is compromised, the others remain intact. If you need to abandon a phone number because it has been linked to your real identity, you delete that Sudo and create a new one — your other identities and their associated accounts are unaffected. This is fundamentally different from having a single phone number and email that, once compromised, expose your entire digital life.

MySudo is best suited for people who need to manage multiple separate identities for different aspects of their life. It is not the most anonymous option (it does require an app store account to download), but it provides the most structured and user-friendly approach to identity compartmentalization. If you interact with many services and want to prevent any single data breach from cascading across your entire identity, MySudo is the most practical tool for the job.

MySudo uses end-to-end encryption for Sudo-to-Sudo calls and messages. When two MySudo users communicate, their conversation is encrypted such that Anonyome Labs (the company behind MySudo) cannot read the content. Calls and messages to non-MySudo users (regular phone numbers) traverse the standard telephone network and are not end-to-end encrypted — they have the same security properties as a regular phone call or text message.

The app stores data locally on your device with device-level encryption. Email sent through Sudo email addresses uses TLS in transit but is not end-to-end encrypted at rest on Anonyome's servers (unless communicating with another Sudo email). The private browser built into each Sudo uses tracker blocking and cookie isolation to prevent cross-site tracking. The encryption architecture is adequate for compartmentalization but is not designed for the threat model of state-level adversaries intercepting communications — for that, pair Sudo phone numbers with Signal or another E2E-encrypted messenger.

MySudo requires downloading the app from the Apple App Store or Google Play Store, which links the download to your Apple ID or Google account. This is the most significant anonymity limitation — unless you have an anonymous app store account (e.g., an Apple ID created with an anonymous email and funded with cash-purchased gift cards), the download is linked to your real identity.

Once installed, MySudo does not require additional identity verification. You create Sudos without providing your real name, address, or any personal information. The phone numbers and email addresses are generated by MySudo and are not tied to your identity in public databases. However, Anonyome Labs does know the mapping between your device and your Sudos, which means they could theoretically provide this information in response to a legal request. For maximum anonymity, use MySudo from a device that is not associated with your real identity.

MySudo is not open source. The application code, the backend infrastructure, and the identity management system are all proprietary to Anonyome Labs. You cannot independently verify the encryption claims, the data retention policies, or the compartmentalization guarantees through code review.

Anonyome Labs has published information about their security architecture and has engaged with the privacy community, but no independent security audit results have been made publicly available. The app has been recommended by privacy advocates including Michael Bazzell (a former FBI cyber investigator who specializes in privacy and OSINT), which provides a degree of expert validation. However, the closed-source nature means you are fundamentally trusting Anonyome Labs to implement their privacy claims correctly.

Anonyome Labs, Inc. is incorporated in the United States, specifically in Salt Lake City, Utah. The United States is a Five Eyes member with broad surveillance capabilities and legal mechanisms for compelling data disclosure, including National Security Letters that can come with gag orders preventing the company from disclosing the request.

This jurisdictional exposure is the most significant concern with MySudo. Anonyome Labs processes your Sudo phone numbers and email through their infrastructure, which means they have technical access to metadata (which Sudo called which number, when, for how long) even if they cannot read encrypted Sudo-to-Sudo content. A U.S. court order or National Security Letter could compel Anonyome Labs to provide this metadata. For crisis privacy scenarios involving U.S. government surveillance, MySudo's compartmentalization provides practical privacy but not immunity.

Anonyome Labs has operated MySudo since 2017 without a publicly known data breach or security incident. The company was founded by privacy researchers and has maintained a consistent focus on consumer privacy tools. MySudo has grown steadily through recommendations from the privacy community rather than through aggressive marketing.

The primary trust signal is Michael Bazzell's longstanding recommendation of MySudo in his books and podcast — Bazzell's reputation in the OSINT and privacy community means his endorsement carries weight. The company has been transparent about their data handling in privacy policy documents, and they have responded to community questions about their practices. However, the combination of U.S. jurisdiction and closed-source code means that trust ultimately rests on the company's reputation rather than verifiable technical guarantees.

MySudo is exceptionally easy to use. The app guides you through creating your first Sudo in under a minute — you choose a name (any name you want), and MySudo provisions a phone number and email address. You can customize the Sudo with a photo and color for easy visual identification. Switching between Sudos is a single tap.

Making calls and sending texts from a Sudo feels identical to using your phone's native dialer, except the recipient sees your Sudo number instead of your real number. The email interface is functional and handles attachments and formatting. The private browser is basic but effective for isolating browsing sessions. The overall experience is polished and consumer-friendly — this is not a tool designed for hackers, it is designed for anyone who wants more control over their personal information. The learning curve is minimal.

MySudo is available on iOS and Android. There is no desktop application, no web interface, and no Linux support. The app is mobile-only by design, as it is fundamentally a phone number and messaging tool.

On both iOS and Android, the full feature set is available: multiple Sudos, phone calls, SMS, email, and private browsing. The iOS app is generally considered more polished, as it was the original development platform. Feature parity between iOS and Android is good, with both platforms receiving regular updates. The lack of desktop support means you cannot use Sudo phone numbers or email from a computer, which is a limitation for people who prefer to work from a desktop.

MySudo offers a free tier that includes one Sudo with limited features. Paid plans (SudoMax) start at approximately $5/month and provide up to 9 Sudos with expanded call minutes, texts, and email. Payment is handled through the Apple App Store or Google Play Store, which means the payment is linked to whatever payment method is associated with your app store account.

For anonymous payment, create an Apple ID or Google account funded with cash-purchased gift cards. On iOS: buy an Apple Gift Card with cash at a retail store, create a new Apple ID with an anonymous email address, and redeem the gift card as your payment method. On Android: buy a Google Play gift card with cash, add it to an anonymous Google account, and subscribe through the app. This adds friction but achieves payment anonymity. MySudo does not accept cryptocurrency directly.

Start by setting up an anonymous app store account if you want to avoid linking MySudo to your real identity. On iOS: create a new Apple ID using an anonymous ProtonMail address, then fund it with a cash-purchased Apple Gift Card. On Android: create a new Google account with an anonymous email and fund it with a cash-purchased Google Play gift card. Sign into this account on your device (or a secondary device).

Download MySudo from the app store and open it. The app will prompt you to create your first Sudo. Choose a name that fits the context you will use this identity for — if this Sudo is for financial services, you might name it something generic. MySudo will provision a phone number (you can choose the area code) and an email address. Set up a Sudo for each major category of your digital life: one for financial services, one for travel bookings, one for healthcare, one for general shopping, and one for your anonymous online presence.

Test each Sudo by making a call, sending a text, and sending an email. Verify that you can receive SMS verification codes — this is the primary use case for crisis privacy. Register your privacy-sensitive accounts (VPN, encrypted email, financial services) using Sudo phone numbers instead of your real number. If you need to abandon any identity in the future, you can delete that Sudo without affecting the others. Store a record of which Sudo is used for which service in your password manager, so you can manage the compartmentalization systematically rather than losing track.
