<p>Authorization is associated with a client's encryption key identifier: <strong>auth_key_id</strong>. No additional parameters need to be passed into methods following authorization. </p>

<p>To log in as a <a href="/bots">bot</a>, follow <a href="/api/bots">these instructions »</a>.</p>

<p>Example implementations: <a href="https://github.com/DrKLO/Telegram/blob/master/TMessagesProj/src/main/java/org/telegram/ui/LoginActivity.java">telegram for android</a>, <a href="https://github.com/tdlib/td/tree/master/td/telegram/SendCodeHelper.cpp">tdlib</a>.</p>
|
||
<p>To show a nicely formatted and validated phone number field, the <a href="/constructor/help.countriesList">help.countriesList</a> constructor can be obtained using the <a href="/method/help.getCountriesList">help.getCountriesList</a> method.<br>The <a href="/constructor/help.countriesList">help.countriesList</a> config and other configuration values are then used as described <a href="/api/config#country-information-and-login-phone-patterns">here »</a>. </p>
|
||
<p>Then, a text message containing an authorization code is sent to the user's phone using <a href="/method/auth.sendCode">auth.sendCode</a>.<br>However, this is not always the case, if future auth tokens are used: </p>
|
||
<h4><a class="anchor" name="future-auth-tokens" href="#future-auth-tokens"><i class="anchor-icon"></i></a>Future auth tokens</h4>
|

<p>When invoking <a href="/method/auth.logOut">auth.logOut</a> on a previously authorized session, the server may return a <code>future_auth_token</code>, which should be stored in the local database.<br>A <code>future_auth_token</code> is also contained in the <a href="/constructor/auth.authorization">auth.authorization</a> returned when logging in.<br>At all times, the future auth token database should contain at most 20 tokens: evict older tokens as new tokens are added to stay below this limit.<br>When invoking <a href="/method/auth.sendCode">auth.sendCode</a>, all future auth tokens present in the database should be provided to <code>codeSettings.logout_tokens</code>.<br>If any of the future auth tokens matches the account we're trying to login into and the token hasn't expired:</p>
|
||
<ul>
|
||
<li>If <a href="/api/srp">2FA</a> is not enabled, <a href="/method/auth.sendCode">auth.sendCode</a> will is directly return an <a href="/constructor/auth.sentCodeSuccess">auth.sentCodeSuccess</a> constructor with session info, indicating the session is authorized.</li>
|

<li>If <a href="/api/srp">2FA</a> is enabled, <a href="/method/auth.sendCode">auth.sendCode</a> will return a <code>SESSION_PASSWORD_NEEDED</code> RPC error, asking the user to <a href="#2fa">enter the 2FA password</a>, without sending any authorization code. </li>
|

</ul>

<p>Otherwise, the system will send an authorization code using the following logic:</p>

<h3><a class="anchor" name="invalidating-login-codes" href="#invalidating-login-codes"><i class="anchor-icon"></i></a>Invalidating login codes</h3>
|
||
<p>Telegram's servers will automatically invalidate login codes if they are sent by the user to another Telegram chat, either by forwarding them or by sending them inside of a message: however, clients should also manually and immediately invalidate login codes if the user attempts to screenshot or forward a message sent by the login notification service user (ID <code>777000</code>) containing login codes. </p>
|
||
<p>If an incoming message that is:</p>
|
||
<ul>
|
||
<li>Sent by the login notification service user (ID <code>777000</code>)</li>
|
||
<li>AND is a text message (not a media)</li>
|
||
<li>AND contains one or more login codes, defined as a sequence of 5 to 7 decimal digits, optionally interleaved with or followed by any number of <code>-</code> characters (<a href="https://github.com/tdlib/td/blob/07c1d53a6d3cb1fad58d2822e55eef6d57363581/td/telegram/MessagesManager.cpp#L6513">example implementation »</a>)</li>

<li>OR forwarded by the user to any chat</li>

</ul>

<p><a href="/method/account.invalidateSignInCodes">account.invalidateSignInCodes</a> should be invoked, passing the extracted login <code>codes</code> (excluding any <code>-</code> characters). </p>

<h3><a class="anchor" name="test-accounts" href="#test-accounts"><i class="anchor-icon"></i></a>Test Accounts</h3>
|
||
<p>Each phone number is limited to only a certain amount of logins per day (e.g. 5, but this is subject to change) after which the API will return a FLOOD error until the next day. This might not be enough for testing the implementation of User Authorization flows in client applications.</p>
|
||
<p>There are several reserved phone number prefixes for testing that your application handles redirects between DCs, sign up, sign in and 2FA flows correctly. These numbers are only available on <strong>Test DCs</strong> (their IP addresses for TCP transport are available in <a href="https://my.telegram.org/apps">API development tools</a> panel after <a href="https://core.telegram.org/api/obtaining_api_id#obtaining-api-id">api_id was obtained</a>, <a href="https://core.telegram.org/mtproto/transports#uri-format">URI format</a> for HTTPS/WebSocket transport).</p>
|
||
<p>If you wish to emulate an application of a user associated with DC number X, it is sufficient to specify the phone number as <code>99966XYYYY</code>, where YYYY are random numbers, when registering the user. A user like this would always get XXXXX as the login confirmation code (the DC number, repeated five times). Note that the value of X must be in the range of 1-3 because there are only 3 Test DCs. When the flood limit is reached for any particular test number, just choose another number (changing the YYYY random part).</p>
|
||
<p>Do not store any important or private information in the messages of such test accounts; anyone can make use of the simplified authorization mechanism – and we periodically wipe all information stored there.</p>
|
||
<p>Proceed with User Authorization flows in <strong>Production DCs</strong> only after you make sure everything works correctly on <strong>Test DCs</strong> first to avoid reaching flood limits.</p>
|
||
<blockquote>
|
||
<p>To help you with working on production DCs, logins with the same phone number with which the <code>api_id</code> was registered have more generous flood limits.</p>
|
||

<h3><a class="anchor" name="we-are-authorized" href="#we-are-authorized"><i class="anchor-icon"></i></a>We are authorized</h3>
|
||
<p>As a result of authorization, the client key, <strong>auth_key_id</strong>, becomes associated with the user, and each subsequent API call with this key will be executed with that user's identity. The authorization method itself returns the relevant user. It is best to immediately store the User ID locally in a binding with the key.</p>
|
||
<p>Only a small portion of the API methods are available to <strong>unauthorized</strong> users:</p>
