# Change the password hashing algorithm













Redis Enterprise Software securely stores all user passwords using a cryptographic hash function. The default password hashing algorithm is `SHA-256`, but `PBKDF2` is also supported as of Redis Enterprise Software version 7.8.6-13.

You can change the password hashing algorithm using [`rladmin`](http://redis.io/docs/latest/operate/rs/references/cli-utilities/rladmin) or the [REST API](http://redis.io/docs/latest/operate/rs/references/rest-api). When you change the password hashing algorithm, the cluster rehashes the administrator password and passwords for all users, including default users.

## Command-line method

To change the password hashing algorithm from the command line, run [`rladmin cluster change_password_hashing_algorithm`](http://redis.io/docs/latest/operate/rs/references/cli-utilities/rladmin/cluster/change_password_hashing_algorithm):

```sh
rladmin cluster change_password_hashing_algorithm PBKDF2
```

## REST API method

You can [change the password hashing algorithm](http://redis.io/docs/latest/operate/rs/references/rest-api/requests/cluster/change_password_hashing_algorithm#patch-change-password-hashing-algorithm) using a REST API request:

```sh
PATCH /v1/cluster/change_password_hashing_algorithm
{ "algorithm": "PBKDF2" }
```
