Blockstream Jade supports BIP39 passphrases and offers several different frequency and entry methods for users to customize usage to their own particular needs.
Note: Passphrases should be considered an advanced feature and users should only proceed with enabling one if they fully understand the implications of doing so.
Frequency
There are several different frequency options so users can decide exactly when they want to access a passphrase-protected wallet:
- Never: You will not be prompted for a passphrase during login.
- Once: You will be prompted for a passphrase only during the next login event via PIN or Recovery Phrase Login. This option should be chosen to conceal the fact that you may use a passphrase.
- Always: The passphrase entry screen will appear during all login events.
Method
There are two different kinds of passphrase entry methods, one designed for more granular control over a particular passphrase and the other geared towards fast entry of easy-to-remember passphrases:
- Manual: A keyboard will appear that allows you to enter specific characters, one-by-one. This option is the standard for most hardware devices and provides the option to use uppercase and lowercase letters, numbers, and more special characters.
- WordList: This entry method is designed for fast entry of long passphrases that are based on the BIP39 wordlist. A random series of these words can be chosen as a passphrase and Jade will recommend BIP39 word options as you begin typing, which greatly speeds up the entry process. Passphrases using this method are easier to remember and can be typed faster than similarly secure, manual entry ASCII passphrases.
Tip: The WordList method will automatically build your passphrase using the following format: lowercaseBIP39word + <space> + lowercaseBIP39word + <space> + lowercaseBIP39word and so on (for example: "satoshi abandon guard"). Passphrases are case-sensitive and spaces count too, so this is important to remember if you want to enter your passphrase with Manual entry or using another hardware wallet. If you are not exactly sure of how the WordList method works, we recommend using Manual entry.
