Sorry to hear that. Is it Java Edition or Bedrock on which you have issues logging in? ^FS

Im personally not having issues, but hundreds of people in #support on discord.gg/minecrafr either cant log in at all, or crash when logging in on Nintendo Switch. This is a logged issue on the bug tracker, but there is no statement or fix on it currently. 1/2

Java also has major login issues since the last launcher update. Lots of people get a invalid password message, even though its the correct data that works on account.mojang.com and minecraft.net
