Use Microsoft Authenticator for easy, secure sign-ins for all your online accounts using multi-factor authentication, passwordless, or password autofill. You also have additional account management options for your Microsoft personal, work or school accounts. Getting started with multi-factor authentication Multi factor authentication (MFA)provides a second layer of security. When enabled, during login after entering your password, you’ll be asked for an additional way to prove it’s really you. Either approve the notification sent to the Microsoft Authenticator, or enter the one-time password (OTP) generated by the app. The OTP codes have a 30 second timer counting down. This timer is so you never have to use the same time-based one-time password (TOTP) twice and you don’t have to remember the number. The OTP doesn’t require you to be connected to a network, and it won’t drain your battery. You can add multiple accounts to your app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more. Getting started with passwordless Use your phone, not your password, to log into your Microsoft account. Just enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two-step verification process. After you’ve signed in with two factor authentication (2FA), you’ll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more. Microsoft personal, work or school accounts Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain organization resources. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator supports cert-based authentication by issuing a certificate on your device. This will let your organization know that the sign-in request is coming from a trusted device and help you seamlessly and securely access additional Microsoft apps and services without needing to log into each. Microsoft Authenticator may request the following optional permissions, which require your consent. You can continue to use Microsoft Authenticator without granting these permissions. However, some features may be limited or unavailable.

ShareMyCal makes it simple to share access to a calendar — no spreadsheets, group chats, or shared passwords. FEATURES • See the calendar right in the app Add a public Google Calendar link and instantly see what dates are free or booked. • Share access on your terms Share the calendar with others by Sms, email, QR code and more. You choose a nickname for each person — no email address or other personal information about them is ever stored. • Remove access one person at a time See who has connected to your calendar, and remove access for one specific person with a single swipe. If more than one person used the same link, each can be removed individually — without affecting the others. • Request open dates Someone shared their calendar with you? Send a request for a specific date range right from the app, with a calendar file attached, so it's easy for the owner to reply. • Face ID / Touch ID Sign back in quickly and securely with biometric authentication. • Danish, English and German Switch languages right from the app's settings. PRIVACY BY DESIGN ShareMyCal is built to store as little as possible. Your account lives only on your device. When you share a calendar, nothing about the recipient is ever sent anywhere — not their name, not their email, only the nickname you choose yourself. You can remove access at any time, and permanently delete your account from within the app. Requires a Google Calendar set to "Make available to public" in its sharing settings to display in the app.
