How to generate many ERC20 etherium wallets?

Question

Cryptocurrency

Task.
It is necessary to generate approximately 500-1000 addresses for receiving coins on smart contracts (according to the ERC-20 standard)
What is the easiest way to do this?
The security of the wallets is not very important as they will only be used for a very short task.
Therefore, even the option is suitable when we supply an array of phrases as an input, and the wallet address for each phrase as an output.
Maybe there is a wallet that allows you to create many addresses inside?
Googled but couldn't find anything :(
