• Taran: Do you have Libsodium module installed and enabled on your server?

Answer 1

For me executing this query:

UPDATE admin_user SET password = CONCAT(SHA2('xxxxxxxxNewPassword', 256), ':xxxxxxxx:1') WHERE username = 'admin';

Fixed my problem. I found the answer here: https://github.com/magento/magento2/issues/23511

• Shankar Prakash G: this works for me, try this first and move on to other solutions.
• kamlesh.bar: Please remember to replace the xxxxxxxx with the crypt key located in your env.php 'crypt' => [ 'key' => 'xxxxxxxx' ],

Answer 2

Even I got the same notice message when I try to login into Magento2 admin panel, after upgrading Magento2 from 2.3.1 to 2.3.2

For me, it got solved after installing PHP version 7.2 and installing the php7.2-sodium extension.

• Arunprabakaran M: It is working fine

Answer 3

I just got exactly the same warning msg and couldn't log in to my Magento 2 admin backend.

I don't know why this is happening and couldn't find any more info online about this.

My workaround this problem was to run this command

magento admin:user:create

add a new admin user and then connect fine.

I couldn't wait for this to be solved to do my work.

Answer 4

I got the issue when I login to backend after clone site magento 2.

I'm using PHP version 7.2 and i tried to install the php7.2-sodium extension.

apt-get install php-sodium

It work for me.

P/S: I'm using nginx server.

Answer 5

"libsodium" is required for the new magento version. For me i fixed it with installing libsodium and afterwards installing the php extension with pecl:

curl https://download.libsodium.org/libsodium/releases/libsodium-1.0.18.tar.gz -o /tmp/libsodium-1.0.18.tar.gz 
tar -xzf /tmp/libsodium-1.0.18.tar.gz -C /tmp 
cd /tmp/libsodium-1.0.18
./configure && make && make check && make install
pecl install libsodium
echo extension=sodium.so > /usr/local/etc/php/conf.d/sodium.ini (your extension directory may be different)

There is already an ticket on github: https://github.com/magento/magento2/issues/23405

For me installing libsodium-dev and php-sodium (inside a docker container) was not working so compiled it from source and used pecl for the php extension..

Answer 6

I had to remove my admin user and recreate it to fix this issue.

Answer 7

I was stuck with this. For me the solution was to delete all admin account before creating new ones. Somehow a bad account gets in the way of all new accounts? I don't know...

Answer 8

Delete your admin user from the database and create a new one with php bin/magento admin:user:create
