STRIP user since Palm Pilot days!


Update - Thanks to the developers for addressing my concerns! I am locked into a Windows work environment (which I am sure many users are), so a portable option for Windows would seem to be the most widely applicable. To recap, my main Enterprise-level considerations that might make it more work friendly:
1) A portable option - in most locked-down environments, you can’t get admin privileges to install your own applications.
2) To make matters worse, there are often dozens of passwords for different applications/websites in the workplace, all with staggered password lifecycles or expiration dates. Do you always log in to every site in time to change that expiring password before getting locked out - or do you find yourself trapped into a call to IT or a remote help desk to reinstate your account? How about a simple expiration date field that you could sort on to see what passwords you need to change in the coming days?

I hope that the innovation continues to demonstrate the commitment to unsurpassed security and simple interface - but i sure would like to have the option to use my Codebook at work (instead of the cumbersome operation of fat-fingering complex passwords from my phone)!

(And I’ll try to engage more on the forum, too!)

Developer Response

Thanks so much for the kind words and for using Codebook for so long!

We've gotten the request to add portability to Codebook before, but haven't yet decided to pursue it, though it would be a nice addition. Would that be for use with Windows environments, or other operating systems? We can't promise we'll pursue it, making any of the four native apps portable would require a substantial effort.

We agree that a feature for password expiration and reset policies is quite desirable and we hope to get to it before too long. Currently we have some other more high priority efforts under way, but it's definitely on our list.

Please feel free to continue this conversation on our discussion forum:

Wonderful software!!

I’m a long time user of Codebook (also when it was Strip). It’s very powerful, but developers are slow to update. iPhone X has been out for a while now and I still have to manually type in a passcode to unlock the app. They took forever with Touch ID and now Face ID seems to be taking the same route.

Super quick response from developers. This will keep me as a user for a long time. You guys are awesome! Face ID works wonderfully!!

Developer Response

Thanks for the candid criticism and sorry for the trouble! Face ID should be ready to roll in the version you're using (3.5.0). You can enable Face ID authentication for Codebook by logging into Codebook and going to More > Settings > Login Settings > Enable Face ID Login. Please feel free to reach out to our support at if you're experiencing any issues enabling it. Thanks!

Excellent and Secure


Unlike some other password managers, I find Codebook to be very simple to reason about where my data lives and how it is encrypted. You have full control over when and where your encrypted data is backed up off device.

It’s simple to use and easy to sync across devices.

I love that it supports time based one time passwords (TOTP) because Google Authenticator does not persist keys in backups.
