# v1.3.0 Migration Guide

***

Credentials allow user to store all 3rd party API keys into database, and can be easily reused on respective nodes, without having to copy pasting every time.

Credentials are encrypted by an encryption key created using a passphrase. Only user who has access to the key can encrypt/decrypt the credentials. Furthermore, decrypted credentials will never get sent back to client to avoid network spoofing.

Below are a few important guides to help you migrate to v1.3.0:

1. Set `PASSPHRASE` env variable. This is used to generate an encryption key used to encrypt/decrypt your credentials
2. Set `SECRETKEY_PATH` env variable. To persist your encryption key, specify the location where encryption key is being saved.

A typical `.env` file should looks like this:

```sh
PORT=3000
PASSPHRASE=MYPASSPHRASE
DATABASE_PATH=/root/.flowise
SECRETKEY_PATH=/root/.flowise
LOG_PATH=/root/.flowise/logs
```

3. Node version. There will be warning message shown on the top right side of a node if the version is outdated. This means there is a new changes on the node, and you should delete and re-add it from the menu list.
