Questions people ask
Is Markero really end-to-end encrypted?
Yes, messages are encrypted in your browser with a PGP Curve25519 keypair before they reach the servers, which store only ciphertext and cannot read messages.
Do I need an email or phone number to sign up?
No, Markero only asks for a username and a password, so there is no email or phone number to link your account to your identity.
Do I need to install an app to use Markero?
No, Markero runs in your browser, though a native Android app is also available with push notifications.
How does Markero secure my account?
Two-factor authentication (TOTP) is available on every account and strongly recommended; your private key is encrypted on your device and recovery codes are provided as a backup.
Where is Markero hosted, and is it free?
Markero's servers are hosted in the European Union under GDPR, and the service is free forever with no ads or paywalled features.
