Description by Zetetic LLC Written by the developer, not by AppBrain. Click to read.
Codebok Password Manager provides powerful and complete data encryption, a flexible data model, automatic sync with Codebook Cloud, and Password AutoFill.

Codebook is free to download and use. Automatic sync with Codebook Cloud requires a subscription.

Codebook has been protecting sensitive information on mobile devices since the days of the Palm Pilot! It protects your passwords and personal information from unauthorized access by would-be crackers, malicious thieves, and snoopy coworkers. Stop using the same password for all your accounts! Codebook generates strong, random passwords and keeps them for you, protected by your master password and powerful encryption.

With a subscription to Codebook Cloud, Codebook will keep your passwords and other sensitive data in sync across all your devices.

Features:

* Fast login with Touch ID
* Full support for AufoFill Passwords in macOS
* Universal keyboard shortcut for filling in passwords in any app
* Automatic background sync with Codebook Cloud
* Support for user-initiated sync over Dropbox, Drive, and Desktop WiFi
* Full text search as you type across all your records and fields
* Auto-lock timer allows you to keep Codebook temporarily unlocked while you work
* Auto-lock can also be triggered by screen-saver and sleep
* Configurable field masking to hide sensitive data from view
* Erases clipboard when information is copied to be pasted in other apps after two minutes
* Includes 200 gorgeous color icons for personalizing your records
* Generates two-step verification (TOTP) codes
* Scans QR codes with main camera
* Store sensitive Image files and PDF documents (10MB max)
* Scan and save data from QR codes directly to your entries
* The History view provides you a quick look into when you last changed your passwords
* The Password Review feature checks a password for breaches in the HaveIBeenPwned.com database of over half a billion hacked passwords

Use Stronger Passwords:

* Codebook helps you remember stronger passwords, but also to generate them
* The password generator allows you to generate random passwords from several common character sets, and adjusts for bias
* The password generator also supports Diceware passwords, both the Reinhold and Electronic Frontier Foundation variants

Customize Away:

* Personalize categories to match your organizational style
* Customize your entries including usernames, passwords, websites, notes and create your own fields and labels
* Note records can be created in any category to store free-form text
* Store any information you want--no restrictive templates!
* Store URL connection strings (e.g. SSH, AFP, SFTP) to launch other applications directly
* Star your Favorites to get at them quickly and sort them to the top of search results

Encryption and Password Protection:

* Uses the open source, encrypted database engine SQLCipher for all data storage
* The encryption used is 256-bit AES in CBC mode
* Master Password key derivation uses 256,000 rounds of PBKDF2 SHA-256
* Every encrypted database has its own random initialization vector
* Every page of storage has its own random initialization vector and HMAC protection
* Hardware-accelerated using CommonCrypto for speed and reduced battery consumption
* All sync data is encrypted with a completely random Sync Key
