# MinIO Multi-user Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO supports multiple long term users in addition to default user created during server startup. New users can be added after server starts up, and server can be configured to deny or allow access to buckets and resources to each of these users. This document explains how to add/remove users and modify their access rights.

## Get started

                        responseData.setMimeType(mimeTypeHelper.getContentType(null, file.getName()));
                    }

                    if (contentLengthHelper != null) {
                        final long maxLength = contentLengthHelper.getMaxLength(responseData.getMimeType());
                        if (responseData.getContentLength() > maxLength) {

  }

  public void testNewParameterizedTypeWithWrongNumberOfTypeArguments() {
    assertThrows(
        IllegalArgumentException.class,
        () -> Types.newParameterizedType(Map.class, String.class, Integer.class, Long.class));
  }

  public void testToString() {
    assertEquals(int[].class.getName(), Types.toString(int[].class));
    assertEquals(int[][].class.getName(), Types.toString(int[][].class));

    settableFuture.set(null);
    assertThat(getDone(stackDepthCheck))
        .isLessThan(Thread.currentThread().getStackTrace().length + 100);
  }

  private static final class LongHolder {
    long count;
  }

  private static final int ITERATION_COUNT = 50_000;
  private static final int DIRECT_EXECUTIONS_PER_THREAD = 100;

    assertThat(stats.hitRate()).isEqualTo(0.0);
    assertThat(stats.missCount()).isEqualTo(1);
    assertThat(stats.missRate()).isEqualTo(1.0);
    assertThat(stats.loadCount()).isEqualTo(1);
    long totalLoadTime = stats.totalLoadTime();
    assertThat(totalLoadTime).isAtLeast(0);
    assertThat(stats.averageLoadPenalty()).isAtLeast(0.0);
    assertThat(stats.evictionCount()).isEqualTo(0);

    cache.getUnchecked(one);

  public PairedStats snapshot() {
    return new PairedStats(xStats.snapshot(), yStats.snapshot(), sumOfProductsOfDeltas);
  }

  /** Returns the number of pairs in the dataset. */
  public long count() {
    return xStats.count();
  }

  /** Returns an immutable snapshot of the statistics on the {@code x} values alone. */
  public Stats xStats() {
    return xStats.snapshot();
  }

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

## How it looks { #how-it-looks }

    assertThrows(IndexOutOfBoundsException.class, () -> sink.putBytes(new byte[8], 0, 16));
    assertThrows(IndexOutOfBoundsException.class, () -> sink.putBytes(new byte[8], 0, -1));
  }

  /**
   * This test creates a long random sequence of inputs, then a lot of differently configured sinks
   * process it; all should produce the same answer, the only difference should be the number of
   * process()/processRemaining() invocations, due to alignment.

        }

        final PathMappingHelper pathMappingHelper = ComponentUtil.getPathMappingHelper();
        final SystemHelper systemHelper = ComponentUtil.getSystemHelper();
        final long totalTime = systemHelper.getCurrentTimeAsLong();

        final CrawlingInfoHelper crawlingInfoHelper = ComponentUtil.getCrawlingInfoHelper();
