Highly Recommended - the One & Only Password App You Need

I work in technology for big firms handling lots of cloud applications, and between my job and my personal life this means that I have hundreds of separate passwords to keep track of along with their temporary two-factor time-based authentication codes. Codebook does it all securely and safely while allowing me to synchronize password data across multiple devices such as my phone and my computer without the use of a third-party cloud provider such as Google.

This means that my data is safe & secure and never leaves my control nor is it used to try to sell me stuff. I have been using this application for almost a decade, and I have found the developer to be both responsive and a thoughtful fellow who responds to to user requests while only adding features in a way that makes sense and keeps the app lightweight, fast, and responsive. I have gifted paid copies of this app to my loved ones, and I highly recommend this app!!

Long Time User Since Original Codebook

Love this app. I used to use the original Codebook app when it first came out on the iPod touches years ago. I loved it. I redownloaded the old Codebook and then stumbled upon their new Codebook app. Apparently the old Codebook is no longer supported by Dropbox, and with my large amount of notes on the old app I decided to migrate them into the new Codebook version. I’m super interested in purchasing the full version, especially knowing it’s not only a password keeper app but also where I can keep my private notes and ideas. However, my greatest complaint is the lack of dates on the notes. I have so many notes that migrated over, however none have any dates as to when I first wrote them. Instead, all the notes are categorized by alphabetical order. I love they kept with the old simple note style, but I strongly prefer the old original Codebook version that categorized notes by date order. Unless I was still able to see the date recorded as to when I first created that note, this app could have been perfect and I would’ve been more than happy to dish out for the paid version.
It’s such a minor thing too, you would think they’d let you categorize your notes by date created.

Developer Response ,

Hi Simply Claire,

Thanks very much for your support of Codebook and for writing this review. There's a view within Codebook called the Journal view, and it closely mimics the old Codebook (Secure Notebook) interface. Within this view you can sort your notes by created or updated date. It's located under [More] > Journal. You can edit your tab bar order (at the bottom of the screen) to have the Journal view first, so when you first launch Codebook it will be displayed right away. To do this, tap the [More] tab bar icon, tap edit in the upper right hand corner, then drag the Journal into the first position (replacing Categories). We'd be happy to assist if you have any questions when attempting these steps. Please feel free to reach out to us at

Excellent Password Manager full of options

I’ve been using this password manager for years and I love it. I will however say it’s for the technically savvy. If you’re only using it locally (e.g. one iPad) then I would say everything is easy. However if you plan to sync via cloud services you have to go through a few steps, and remember to always sync. It does not automatically sync to the cloud.

The most important feature they have is giving me the choice of where the database is stored. There is no option to store the database with Codebook servers because it’s not a service they offer. Instead I can keep the database totally within my ecosystem by using the WiFi sync option. Since I at least have trust in Codebook encryption security, I’ve chosen to sync via Dropbox. But the beauty of this is it’s my Dropbox account.

My takeaway of the above is since Codebook doesn’t have servers, the hackers are unlikely to bother trying to hack Codebook encryption. First they’ve have to crack Codebook encryption technology, but it would only be useful when they find where users have stored the database. This is the most clever solution for a password manager that I’ve come across!

Keep up the great work Codebook team!

p.s. Their support team is super responsive! I’ve contact them a handful of times with questions and almost always get a thorough response the same day!
