Frequently Asked Questions
Should I password protect my tax documents before emailing them?
Yes — always. Email is not encrypted in transit by default, and inboxes are a common target for data breaches. A password-protected PDF ensures that even if the email is intercepted or the recipient's inbox is compromised, your SSN and financial data remain protected. Your CPA will expect a password and appreciate the security practice.
What encryption does MiOffice use to protect the PDF?
MiOffice applies 256-bit AES encryption, which is the same standard used by banks and the IRS. The encryption is applied privately — your files are never shared or stored.
What password should I use for tax documents sent to my CPA?
Use a strong, unique password and share it with your CPA via a separate channel — a text message or phone call, never in the same email as the document. Avoid using your SSN or birth date as the password.
