Username and password based authentication

Below are examples of the code for authentication based on a username and token in different YDB SDKs.

C++

Go (native)

Go (database/sql)

Java

Node.js

Python

Python (asyncio)

C# (.NET)

PHP

auto driverConfig = NYdb::TDriverConfig()
   .SetEndpoint(endpoint)
   .SetDatabase(database)
   .SetCredentialsProviderFactory(NYdb::CreateLoginCredentialsProviderFactory({
      .User = "user",
      .Password = "password",
   }));

NYdb::TDriver driver(driverConfig);

You can pass the username and password in the connection string. For example:

"grpcs://login:password@localohost:2135/local"

You can also explicitly pass them using the ydb.WithStaticCredentials parameter:

package main

import (
  "context"
  "os"

  "github.com/ydb-platform/ydb-go-sdk/v3"
)

func main() {
  ctx, cancel := context.WithCancel(context.Background())
  defer cancel()
  db, err := ydb.Open(ctx,
      os.Getenv("YDB_CONNECTION_STRING"),
      ydb.WithStaticCredentials("user", "password"),
  )
  if err != nil {
      panic(err)
  }
  defer db.Close(ctx)
  ...
}

You can pass the username and password in the connection string. For example:

package main

import (
  "context"

  _ "github.com/ydb-platform/ydb-go-sdk/v3"
)

func main() {
  db, err := sql.Open("ydb", "grpcs://login:password@localohost:2135/local")
  if err != nil {
      panic(err)
  }
  defer db.Close()
  ...
}

You can also explicitly pass the username and password at driver initialization via a connector using the ydb.WithStaticCredentials parameter:

package main

import (
  "context"
  "os"

  "github.com/ydb-platform/ydb-go-sdk/v3"
)

func main() {
  ctx, cancel := context.WithCancel(context.Background())
  defer cancel()
  nativeDriver, err := ydb.Open(ctx,
      os.Getenv("YDB_CONNECTION_STRING"),
      ydb.WithStaticCredentials("user", "password"),
  )
  if err != nil {
      panic(err)
  }
  defer nativeDriver.Close(ctx)
  connector, err := ydb.Connector(nativeDriver)
  if err != nil {
    panic(err)
  }
  db := sql.OpenDB(connector)
  defer db.Close()
  ...
}

public void work(String connectionString, String username, String password) {
    AuthProvider authProvider = new StaticCredentials(username, password);

    GrpcTransport transport = GrpcTransport.forConnectionString(connectionString)
            .withAuthProvider(authProvider)
            .build());

    TableClient tableClient = TableClient.newClient(transport).build();

    doWork(tableClient);

    tableClient.close();
    transport.close();
}

import { Driver, StaticCredentialsAuthService } from 'ydb-sdk';

export async function connect(endpoint: string, database: string, user: string, password: string) {
    const authService = new StaticCredentialsAuthService(user, password, endpoint, {
        tokenExpirationTimeout: 20000,
    })
    const driver = new Driver({endpoint, database, authService});
    const timeout = 10000;
    if (!await driver.ready(timeout)) {
        console.log(`Driver has not become ready in ${timeout}ms!`);
        process.exit(1);
    }
    console.log('Driver connected')
    return driver
}
