What are the restrictions and rules for SDK password?

Password rules for SDK verification: Password rules SDK does not do password verification. Tuya is done by the upper layer, and it is recommended that the customer's password rules: 6-20 digits, must have letters and numbers. The cloud has also verified that the client will make the password sha value, and the cloud will go back to match, similar to 123456, A11111, and other simple passwords, to avoid the occurrence of overly simple passwords.
