Answer 1

This same error has an excellent answer in the StackExchange post This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP.

This error occurs with Magento 2.4.2 when php does not include the sodium php extension.

You can check if this extension is installed with

php -i | grep sodium
sodium support => enabled
libsodium headers version => 1.0.16

To fix this problem install / activate the sodium php extension.

For Xampp in php.ini add (or uncomment)

extension=sodium;

Or

sudo apt install php-libsodium

NOTE the supported PHP version for Magento 2.4 is PHP 7.4
