    WARNING: Vanity addresses generated with this tool may not be widely supported in various wallets anymore. They may consider the addresses generated with this tool to be "legacy" wallets. Therefore I no longer recommended generating vanity addresses using this method.

After seeing the recently posted How To Generate A Tezos Vanity Address, I thought I'd share a method I've used to generate a vanity address that has the benefit of being able to easily be restored or transferred to another wallet from a seed phrase backup.
Most of the credit goes to Stephen Andrews. I've just slightly modified some of the code he wrote to get it to work the way I want.
Everything below assumes you are working from the Linux command line (tested in Debian/Ubuntu distributions):
First, clone Stephen Andrews' eztz repository from github:
git clone -b vanity https://github.com/stephenandrews/eztz

Then enter the newly created directory and the vanity subdirectory:
cd eztz/vanity

Next, install the needed dependencies with npm (use apt install npm if you don't have npm installed):
npm install

Grab my customized index.js which I called vanity.js here:
wget https://gist.github.com/baketzforme/e27d46d70e949ea9953b11902c2fa4fe/raw/vanity.js

Finally you're ready to generate your vanity address. The below example will search for an address that starts with tz1TERM.
node vanity.js TERM

Example output:
node vanity.js Tz  
Searching for tz1Tz  
Checked 119 hashes  
Found match:  
tz1TzrmTBSuiVHV2VfMnGRMYvTEPCP42oSM8  
giant grunt jewel suit scatter surface chaos tumble radar fortune rifle frost essence motion worry  

You can also optionally include a password. This adds a little more security because the seed words without the password will not import the same address.
node vanity.js TERM PASSWORD

Example output:
node vanity.js Tz secretPassword  
Searching for tz1Tz  
Checked 630 hashes  
Found match:  
tz1TzijVFZT1QmohdSfsBnVAQQa48eWL2xfH  
ramp sea drama balance scale mixed chapter dream hundred sweet language chuckle reform alert clock  

The above seed phrase without the password generates the following address: tz1aBFAMsDGHqnmrhgGhjx9kowjFLJMXEbsC
Just make sure to backup your seed phrase and your password if you use one, or else any funds stored on the generated account could be lost forever.
Enjoy!
