{{DISPLAYTITLE:''Bedrock Edition'' protocol/Login Sequence}}
{{exclusive|bedrock}}

This page describes the usual login sequence for the {{BE}} protocol after a transport connection has been established. Packet order can vary with encryption, resource-pack negotiation, and server behavior. For packet fields, see [[Minecraft:Bedrock_Edition_protocol/Packets|Packets]]. The packet descriptions below are based on Mojang's protocol 2193 schemas for [[Minecraft:26.51]].<ref name="schema-release">[https://github.com/Mojang/bedrock-protocol-docs/releases/tag/v1.26.51 Mojang: Protocol 2193 schema release]</ref>

== Typical sequence ==

The following is a general outline, not a guarantee that every connection sends each packet in exactly this order.

# C→S: [[Minecraft:Bedrock_Edition_protocol/Packets#Request_Network_Settings|Request Network Settings]]
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Network_Settings|Network Settings]]
# C→S: [[Minecraft:Bedrock_Edition_protocol/Packets#Login|Login]]
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Server_To_Client_Handshake|Server To Client Handshake]] (when application-layer encryption is used)
# C→S: [[Minecraft:Bedrock_Edition_protocol/Packets#Client_To_Server_Handshake|Client To Server Handshake]] (when application-layer encryption is used)
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Play_Status|Play Status]] with the <code>LoginSuccess</code> status
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Packs_Info|Resource Packs Info]] (if the server offers resource packs)
# C↔S: Resource-pack negotiation and transfer (if needed)
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Pack_Stack|Resource Pack Stack]] (if resource packs are offered)
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Start_Game|Start Game]] and world-initialization packets
# C→S: [[Minecraft:Bedrock_Edition_protocol/Packets#Set_Local_Player_As_Initialized|Set Local Player As Initialized]]
# S→C: [[Minecraft:Bedrock_Edition_protocol/Packets#Play_Status|Play Status]] with the <code>PlayerSpawn</code> status

== Network settings ==

After the transport connection is established, the client sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Request_Network_Settings|Request Network Settings]]''', including its protocol version. The server responds with '''[[Minecraft:Bedrock_Edition_protocol/Packets#Network_Settings|Network Settings]]''', which specifies the compression threshold and algorithm. The client uses the negotiated settings for subsequent game packets.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/request-network-settings-packet/ Mojang: Request Network Settings]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/network-settings-packet/ Mojang: Network Settings]</ref>

== Login and encryption ==

The client sends a '''[[Minecraft:Bedrock_Edition_protocol/Packets#Login|Login]]''' packet containing its protocol version and connection request. The server validates the request and authenticates the client.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/login-packet/ Mojang: Login]</ref>

When application-layer encryption is used, the server sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Server_To_Client_Handshake|Server To Client Handshake]]'''. The client responds with '''[[Minecraft:Bedrock_Edition_protocol/Packets#Client_To_Server_Handshake|Client To Server Handshake]]'''; encrypted communication then continues. Connections that do not use application-layer encryption omit this exchange.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/server-to-client-handshake-packet/ Mojang: Server To Client Handshake]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/client-to-server-handshake-packet/ Mojang: Client To Server Handshake]</ref>

After login succeeds, the server sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Play_Status|Play Status]]''' with the <code>LoginSuccess</code> status. This marks successful login; it does not by itself mean that the player has spawned in the world. The relative order of this packet and resource-pack negotiation can vary by server.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/play-status-packet/ Mojang: Play Status]</ref>

== Resource packs ==

If the server offers resource packs, it sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Packs_Info|Resource Packs Info]]'''. The client can cancel or report that it is downloading the offered packs using '''[[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Pack_Client_Response|Resource Pack Client Response]]'''. Pack data is transferred as needed. When downloads finish, the client reports completion; the server then sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Pack_Stack|Resource Pack Stack]]''' to specify the packs to apply. After applying the stack, the client reports that the stack is finished using '''[[Minecraft:Bedrock_Edition_protocol/Packets#Resource_Pack_Client_Response|Resource Pack Client Response]]'''. Servers that do not offer packs can skip this negotiation; resource-pack responses are not required in that case.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/resource-packs-info-packet/ Mojang: Resource Packs Info]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/resource-pack-client-response-packet/ Mojang: Resource Pack Client Response]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/resource-pack-stack-packet/ Mojang: Resource Pack Stack]</ref>

== Starting the game ==

The server sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Start_Game|Start Game]]''' and the packets needed to initialize the world. These can include '''[[Minecraft:Bedrock_Edition_protocol/Packets#Creative_Content|Creative Content]]''', '''[[Minecraft:Bedrock_Edition_protocol/Packets#Biome_Definition_List|Biome Definition List]]''', and '''[[Minecraft:Bedrock_Edition_protocol/Packets#Level_Chunk|Level Chunk]]''' packets, depending on the connection and the data the client needs. The client sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Set_Local_Player_As_Initialized|Set Local Player As Initialized]]''' when it is ready; the server sends '''[[Minecraft:Bedrock_Edition_protocol/Packets#Play_Status|Play Status]]''' with the <code>PlayerSpawn</code> status to indicate that the player has spawned. World-initialization packets can vary in presence and order.<ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/start-game-packet/ Mojang: Start Game]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/set-local-player-as-initialized-packet/ Mojang: Set Local Player As Initialized]</ref><ref>[https://mojang.github.io/bedrock-protocol-docs/1.26.51/packets/play-status-packet/ Mojang: Play Status]</ref>
