Does Coinbase store a recovery phrase?

I'm curious to understand the security measures employed by Coinbase when it comes to safeguarding users' funds. Specifically, I'm wondering if Coinbase stores a recovery phrase for its users' digital wallets. It's crucial for users to have access to their recovery phrase in case they forget their login credentials or lose access to their device. So, does Coinbase retain a copy of this sensitive information, or do users need to keep it SAFE on their own? And if Coinbase doesn't store it, what steps does the platform take to ensure users can regain access to their funds in case of emergencies?
