I just installed mysql on mac from Homebrew 

brew install mysql mysql -V mysql Ver 8.0.11 for osx10.13 on x86_64 (Homebrew)

from terminal it works and I can login to mysql but from Sequel Pro it says

enter image description here

Unable to connect to host 127.0.0.1, or the request timed out.

Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

MySQL said: Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 2): image not found

can't figure out what I am missing

Reset to default

This is because Sequel Pro is not ready yet for a new kind of user login, as the error states: there is no driver.

mysql + homebrew

Basically you will have to perform some actions manually, however- your database data won't be deleted like in solution below

  • Go to my.cnf file and in section [mysqld] add line:

    default-authentication-plugin=mysql_native_password

  • Login to mysql server from terminal: run mysql -u root -p, then inside shell execute this command (replacing [password] with your actual password):

    ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '[password]';

  • exit from mysql shell with exit and run brew services restart mysql.

Should work.

Quick fix (destructive method)

Quick fix for non-homebrew installs:

Apple Logo > System Preferences > MySQL > Initialize Database, then type your new password and select 'Use legacy password'

After restart you should be able to connect. Do it only on fresh installs, because you may lost your db tables otherwise.

my.cnf

The my.cnf file is located in /etc/my.cnf on Unix/Linux

Alternatives

For those who is still struggling with Sequel Pro problems: Sequel Pro was a great product, but with tons of unresolved issues and last release being dated to 2016 perhaps it's a good idea to look for some alternatives. There is a fork of SequelPro called SequelAce that seems to be pretty stable and up-to-date, it keeps similar functionality, similar look and feel, yet at the same time it is devoid of old Sequel Pro problems

I can't find MySQL in System Preferences
thanks for explain, but can't locate my.cnf file on my machine(macOS High Sierra 10.13.5)
If there is no such file, you will have to create one: please, have a look at this thread: stackoverflow.com/questions/7973927/…
This worked great on a fresh brew install mysql using /usr/local/etc/my.cnf
I didn't use a password, so I used ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY ''; - this worked for me

TL;DR: Sequel Pro is dead since 2016. Don't downgrade your DB because of a tool. Move on to an alternative tool.

Update 2020: Sequel Pro is officially dead but unofficially alive! You can find the "nightly" builds that don't have this issue (i.e. support Mysql 8 auth) in here: https://sequelpro.com/test-builds

Update 2021: Sequel Ace is a good similar alive alternative: https://github.com/Sequel-Ace/Sequel-Ace#installation (Credits to Maciej Kwas's answer)

All the other solutions here are recommending changing your DB settings (making it less secure, as advertised by MySQL) for the tool you are using. That's not acceptable to me.

I have always been a huge fan of Sequel Pro, even donated to it. But, with all my passion and love, I am sorry if the tool doesn't have any release since 2016. YOLO, and I need to move on!

The alternative I found (from https://stackoverflow.com/a/55235533/2321594, thanks to @arcseldon) is DBeaver which supports MySQL 8's new authentication (non-legacy) method.

PS. The only trick in the tool side, not the DB side is when you are creating a MySQL 8 connection you might need to go to "Driver Properties" (later can be found in Edit Connection) and turn the value of allowPublicKeyRetrieval to true.

I needed this to connect to my MySQL container created using Docker. To have the IP of MySQL be visible to the outside, for any other application in your ecosystem (not just this tool), you should either create a new user in MySQL, or pass -e MYSQL_ROOT_HOST=% in the run-time or as an ENV.

I believe @Aidin you gave me a downvote just because my answer does not resolves the OP problem. It's just a local development and local settings- so what's the point? Do I really have to leave software I am familiar with and I like to work with just because you say so?
Please don't take it personal @MaciejKwas. Despite providing more explanation here, which I appreciate, I am still standing by my vote. The three main reasons are: 1) Maintaining different setup between dev/prod is not recommended in modern software development. It's, in fact, factor X of 12factor.net/dev-prod-parity . 2) People can use these tools for checking prod as well. You can create a ssh-tunnel/proxy and get to your prod DB via a GUI tool. In such cases, downgrading the DB auth is not an option. 3) Not adapting to change and upgrade is something I don't value, personally.
I'm coming back to a MySQL project I haven't ran locally in a couple years b/c it's been rock solid and i'm so sad to find out that sequel pro is dead :(
Also choose the MySQL +8 driver in DBeaver as there are multiple drivers to choose from. In the driver properties set allowPublicKeyRetrieval to true and save.
OMG, you made my day with Sequel Ace tip! Thank you!

Sequel Pro is officially dead and no longer supports newer MySql features. However, the good news is that it was replaced by Sequel Ace which is available on GitHub and App store. The app is free of charge and looks like official replacement for Sequel Pro as the post was made by one of the collaborators of Sequel Pro.

Ps. I decided to post this as an answer as others have not mentioned that there is now an up-to-date replacement for Sequel Pro

  1. Assuming you don't have a mysql configuration, echo the following to ~/.my.conf.

    [mysqld] default-authentication-plugin=mysql_native_password

  2. Sign into mysql with mysql -u root -p

  3. Set the root user password with ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '[PASSWORD]'; where [PASSWORD] is a password of your choosing.

  4. Restart mysql with e.g. brew services restart mysql

It's a great solution if you realllllllllllly don't care about anything and it's just a local, dev, test-only, practice, one-time, throw-away database. Read stackoverflow.com/a/56509065 for the explanation of why it's a bad idea to change DB, because of a tool.

If you connect to MySQL via [email protected], make sure that you reset its password too!

ALTER USER 'root'@'127.0.0.1' IDENTIFIED WITH mysql_native_password BY '[password]';

I am getting: ERROR 3009 (HY000): Column count of mysql.user is wrong. Expected 50, found 49. Created with MySQL 80012, now running 80013. Please use mysql_upgrade to fix this error.
try this on the terminal: mysql_upgrade --force -uroot -p
mysql_upgrade has now been deprecated and won't work, use mysqld --upgrade=FORCE instead.

It's working for me. if you are getting this error :

Unable to connect to host 127.0.0.1, or the request timed out.

Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

If anyone facing this issue and installed MySQL version > 8 through .dmg file; downloaded it from the official link. In that case please use this guideline. I am adding the same details below in case the link will not be available in the future.

This issue is because you're using the new Strong Password Encryption which is a new feature in MySQL 8, if you installed MySQL 8 using the .dmg file, you can go to System Preferences > MySQL and then click on Initialize Database type your password and select the second option Use Legacy Password Encryption.

Using a old style password worked for me. Thank you!

Don't downgrade! Don't compromise your security.

The only thing that worked for me (even Sequel Ace did not work) was to create a new user and use that one to login.

This works with both Sequel Ace and Sequel Pro.

Use this command:

mysql -e "CREATE USER 'admin'@'localhost' IDENTIFIED BY 'password'; GRANT ALL ON *.* TO 'admin'@'localhost';

Then simply use that user to login from either app and it will work.
