No phone number. No email. No KYC.
Most messaging apps make you hand over a phone number to sign up. That number is your real identity, tied to a SIM, a carrier, and usually your name. Blockd does not ask for one. Create an account in seconds, with no phone number and no email.
A phone number is the single most powerful identifier you can hand an app. It links your conversations to a SIM card, a carrier account, a billing address, and in most countries a government ID. Encryption does not undo any of that.
Carriers and registries connect your number to your legal identity and address.
A number is a lookup key. Share it once and you can be found, contacted, and profiled.
Phone-number apps read your contacts and rebuild your social graph on their servers.
Blockd identifies you by a cryptographic key that you control, not by a number you rent from a carrier. There is nothing to look up, nothing tied to a SIM, and nothing that links the account to your real-world identity.
Your identity is a cryptographic identifier generated on your device. No phone number, no email.
Recovery is a seed phrase plus a passkey that you control. No password to leak, no number to port.
Post-quantum end-to-end encrypted messages, voice, and video. Anonymous by default.
Signal, WhatsApp, and Telegram all tie your account to a phone number. Blockd does not.

Compare Blockd and SignalYes. Blockd requires no phone number and no email to create an account. Your identity is a cryptographic key generated on your device, so there is no number tied to a SIM, a carrier, or your name.
You create a cryptographic identity on your device in seconds. There is no phone number to enter and no email to verify. You are identified by a key you control, not by personal information you hand over.
Recovery is a seed phrase plus a passkey that you hold. Because there is no phone number or password tied to the account, there is nothing to port, phish, or leak through a carrier.
Yes. Every message, voice call, and video call is end-to-end encrypted by default using post-quantum encryption. Removing the phone number removes an identity link, and it does not weaken the encryption.
They use the phone number as your account identity and for contact discovery. It is convenient, but it ties every conversation to a SIM, a carrier, and usually your real name. Blockd takes the other path and uses a key instead.
Yes. The Blockd app is free to download, and Blockd Pro is free for everyone through December 31, 2026, with no code required.
