Evernote has added Reminders and optional new security features to its popular note taking and task management app.  The Reminders feature — which lets users add dates to notes and receive in-app or email notifications — has been initially added to Evernote’s Mac, iOS, and Web services apps.  The feature will make its way onto Evernote for Android and other platforms soon.

Evernote RemindersThe new Reminders feature lets you add a Reminder to a note by simply tapping on the alarm clock icon located at the top of the note on Mac and Web, and at the bottom of the note on iPhone and iPad.  Once your reminder is set, you’ll see the note title appear in the new Reminder section at the top of the note list.  You can change the order of reminders just by dragging them around.  If you choose to set a date and time for when this note must be completed, you’ll get an in-app alarm and, optionally, an email the day a reminder is due.  When you complete your task, tap on the check or, on iOS, swipe to remove the reminder from the list.

Like most things in Evernote, Reminders sync across all versions of the app that support the new feature.  You can get more details about Evernote Reminders and watch a video here.

Evernote has also rolled out three optional security features: Authorized Applications, Two-Step Verification, and Access History.  With authorized applications, you can revoke any Evernote app from your Evernote Web Account Settings.  Once revoked, the Evernote app will request a password the next time its launched.

Two-step verification is also optional, but when you turn it on, it prevents someone from accessing your notes if they have your password, but not your mobile phone.  Two-step verification has already become an common feature on apps from other major software companies such as Apple, Microsoft, Facebook, Google, Dropbox, and Twitter. You can watch a 20-minute video about Evernote’s two-step verification here.

Access History shows you a running list of every time your account was accessed over the past thirty days.  This list includes all the versions of Evernote that you’ve used along with locations and IP addresses.  If you ever suspect that your account was accessed without your knowledge, you can check the history.
