Choose your username
Select a unique username for your SipherMail address (e.g., yourname@siphermail.com). Usernames must be 3-30 characters and can contain letters, numbers, and hyphens.
Create a strong password
Use a strong, unique password. We recommend at least 12 characters with a mix of letters, numbers, and symbols. Your password is never stored in plain text.
Verify your email (optional)
Optionally verify a recovery email address. This helps with account recovery if you forget your password.
Set up two-factor authentication
We strongly recommend enabling 2FA for additional security. You can set this up during signup or later in Settings → Security. See our Two-Factor Auth guide for detailed instructions.
