Source Code local is the default, credentials/token based scheme for flows like JWT . By default local scheme is enabled and preconfigured. You can set strategies.local to false to disable it. Usage To do a password based login by sending credentials in request body as a JSON object: < template > < div > < form @ submit . prevent = " userLogin " > < div > < label >Username < input type = "text" v-model = " login.username " /> < div > < label >Password < input type = "password" v-model = " login.password " /> < div > < button type = "submit" >Submit < script lang = "ts" setup > const login = reactive ({ username: '' , password: '' }) const $auth = useAuth () async userLogin () { try { const response = await $auth. loginWith ( 'local' , { body: login }) console. log (response._data) } catch (err) { console. log (err) } } Backend You'll need a backend server that implement the basics of authentication. As this is very security-sensitive code, we strongly recommend that you use an established authentication library for your backend, too. The backend will, at minimum, need to handle login and logout. It will also, by default, need to include an endpoint to fetch user information (ID, email, etc). This can be disabled with endpoints.user = false if your frontend doesn't need to know anything about your user. In this case, $auth.user will be {} . Login The backend should verify the login credentials, then return a JSON body with the token that the frontend can use to act as this user. The JSON body format is configured in the token section of the local scheme configuration . TIP: If you want to use cookies instead of token-based authentication, use the cookie scheme. The entire backend response is passed through to the loginWith response, so you can pass through additional information about the user, e.g. for authorization (which is out of scope of @nuxtjs/auth). Fetch User The auth module does not persist information about the user, so there needs to be a way to fetch the user's information on e.g. page reload. That's what the user endpoint is for. By default, this is also called after a successful login. If user.autoFetch is true (default) , then a request to endpoints.user is sent immediately after a successful login. That endpoint should respond with the JSON information for a specific user, which is assigned directly to the user property . If you'd prefer to return the user's information directly from the login session, configure user.autoFetch to false, fetch the user information from the loginWith response, and pass it in to setUser . If you want to disable fetching user info entirely, set endpoints.user: false . This will mean the user info endpoint is never called, but will also mean the frontend doesn't know anything about the user; $auth.user will be {} . Options Example for a token based flow: auth : { strategies : { local : { token : { property : 'token' , global : true , // required: true, // type: 'Bearer' }, user : { property : 'user' , // autoFetch: true }, endpoints : { login : { url : '/api/auth/login' , method : 'post' }, logout : { url : '/api/auth/logout' , method : 'post' }, user : { url : '/api/auth/user' , method : 'get' } } } } } Example for a cookie based flow: auth : { strategies : { local : { token : { required : false , type : false , httpOnly : false }, endpoints : { login : { url : '/api/auth/login' , method : 'post' }, } } } } endpoints Additional Information Each endpoint is used to make requests using ohmyfetch. To disable each endpoint, simply set its value to false . token Additional Information Here you configure the token options. property property can be used to specify which field of the response JSON to be used for value. It can be false to directly use API response or being more complicated like auth.token . prefix Default: _token. prefix sets the token prefix in the state. Note: if you are using vuex, the token will only appear in the auth state if the prefix does not start with an underscore ( _ ). required Default: true This option can be used to disable all token handling. global Default: true This determines if the authentication token is automatically included in all custom axios requests. name Default: Authorization Authorization header name to be used in axios requests. type Default: Bearer Authorization header type to be used in axios requests. maxAge Default: 1800 Here you set the expiration time of the token, in seconds . This time will be used if for some reason we couldn't decode the token to get the expiration date. By default is set to 30 minutes. httpOnly Default: false If set to true, the refresh token will be made into a httpOnly cookie. user Additional Information Here you configure the user options. Note that these options should be set in local.user and not in the user endpoints options (local.endpoints.user). Refer to the example above for further clarification. property property can be used to specify which field of the response JSON to be used for value. It can be false to directly use API response or being more complicated like auth.user . autoFetch Default: true By default, auth will load the user's info using a second HTTP request after a successful login. This option disables that request, but does not disable fetching user info from the user endpoint; set endpoints.user: false for that. TIP: Set this to false when you want to return the user info from your login request to save an extra HTTP roundtrip. To do so, get the response from loginWith and pass the data to setUser . Note that, unless you disable the user endpoint with endpoints.user: false you will still need to implement the user endpoint so that auth can fetch the user information on e.g. page refresh. clientId Additional Information Default: false If your backend requires client id, it can be set here. grantType Additional Information Default: false If your backend requires grant type, it can be set here. scope Additional Information Default: false html .shiki span {color: var(--shiki-default);background: var(--shiki-default-bg);font-style: var(--shiki-default-font-style);font-weight: var(--shiki-default-font-weight);text-decoration: var(--shiki-default-text-decoration);}html.dark .shiki span {color: var(--shiki-dark);background: var(--shiki-dark-bg);font-style: var(--shiki-dark-font-style);font-weight: var(--shiki-dark-font-weight);text-decoration: var(--shiki-dark-text-decoration);}html .dark .shiki span {color: var(--shiki-dark);background: var(--shiki-dark-bg);font-style: var(--shiki-dark-font-style);font-weight: var(--shiki-dark-font-weight);text-decoration: var(--shiki-dark-text-decoration);}html .default .shiki span {color: var(--shiki-default);background: var(--shiki-default-bg);font-style: var(--shiki-default-font-style);font-weight: var(--shiki-default-font-weight);text-decoration: var(--shiki-default-text-decoration);}
