# Authenticating with a User and Password
|
|
|
|
For this example, start the server using:
|
|
|
|
```bash
|
|
> nats-server --user myname --pass password
|
|
```
|
|
|
|
You can encrypt passwords to pass to `nats-server` using a simple tool provided by the server:
|
|
|
|
```bash
|
|
> go run mkpasswd.go -p
|
|
> password: password
|
|
> bcrypt hash: $2a$11$1oJy/wZYNTxr9jNwMNwS3eUGhBpHT3On8CL9o7ey89mpgo88VG6ba
|
|
```
|
|
|
|
and use the hashed password in the server config. The client still uses the plain text version.
|
|
|
|
The code uses localhost:4222 so that you can start the server on your machine to try them out.

|
## Connecting with a User/Password
|
|
|
|
When logging in with a password `nats-server` will take either a plain text password or an encrypted password.

|
## Connecting with a User/Password in the URL
|
|
|
|
Most clients make it easy to pass the user name and password by accepting them in the URL for the server. This standard format is:
|
|
|
|
> nats://_user_:_password_@server:port
|
|
|
|
Using this format, you can connect to a server using authentication as easily as you connected with a URL:
|
|
|
|
!INCLUDE "../../\_examples/connect\_userpass\_url.html"
