Magento 2 Magento using its own Technique for password hashing by following below Technique (One of the best Strongest Web Password Encryption algorithms).
[1] Password Hash –
[2] Salt –
[3] SHA256 –
[4] Argon 2ID13 –
Magento 2 Password collection of all above Password algorithms

Magento 2 always stored password as above format
Fist Part=password hash
password hash=6f98f4b6dd20dad5f00f97aa08541fb29c728fc1b8ce32b23bc11c66f792528c
Second Part=Salt=T2izWsU9DcHN1HJ
The last two are the different hash algorithms:
1 is SHA256 and 2 is Argon 2ID13.
This means that the customer’s password was originally hashed with SHA256 and after that, the algorithm was updated with Argon 2ID13 and the hash was re-hashed with Argon.
