# Microsoft Outlook vs Authenticator App

The clearest difference is review sentiment: Microsoft Outlook at 64% against Authenticator App's 20%. Microsoft Outlook also leads on rating (4.8 vs 4.2) and ratings volume (9.3M vs 86). Authenticator App's advantage is ads (none vs shown) and device support (5 vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Microsoft Outlook sells 4 in-app purchases, starting at $1.99 per month and Authenticator App sells 11 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Microsoft Outlook holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Microsoft Outlook has 9.3M ratings behind it against 86, so its average is the more settled of the two. Written reviews point the same way: 64% of Microsoft Outlook's written reviews are positive against 20% of Authenticator App's.

Microsoft Outlook ships an update weekly, Authenticator App every 9 days. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
