Microsoft Announces One-Time Passcode For Office 365 Message Encryption

Earlier this year, Microsoft announced Office 365 Message Encryption service that allowed users to send encrypted mail to anyone. Today, they are announcing the release of One-Time Passcode. With One-Time Passcode, users need not to sign in with a Microsoft account to view an encrypted message.

Previously, when you received a message encrypted with Office 365 Message Encryption, you could view the encrypted message only by using a Microsoft account. Now, with the addition of the One-Time Passcode capability, you can view an encrypted message you receive without having to sign in with a Microsoft account. If you have a Microsoft account, you now have the option to view an encrypted message by selecting one-time passcode instead of signing in with your account.

This capability is now available to everyone in the respective tenants.
