Wonderful software!!

Señor Bushman

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!!

Great app and Great Customer service


Ive been using Codebook for a while now, and it’s great to manage passwords. I recently bought a PC and was having trouble syncing my iPhone and Windows device, Codebook has amazing and patient customer service. We quickly worked through the issue and now I’m all set. Love this app! Also the thumbprint to login is huge!

Excited about a password manager! Codebook is Superb!

In my opinion (which is backed up by many experts), Codebook by Zeteric is the finest password manager available on iOS! Not only is the security legendary, but it is also intuitive.

Additionally, the developer consistently updates and improves this app as appropriate!
