The recommended minimums for PBKDF2, as per OWASP Cheat Sheet Series (https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html), are:
If FIPS-140 compliance is required, use PBKDF2 with a work factor of 310,000 or more and set with an internal hash function of HMAC-SHA-256.
Previous default configuration:
algorithm=SHA1, iterations=185000, hashLength=256
New default configuration:
algorithm=SHA256, iterations=310000, hashLength=256
The default salt length was also updated from 8 to 16.

The recommended minimums for scrypt, as per OWASP Cheat Sheet Series (https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html), are:
Use scrypt with a minimum CPU/memory cost parameter of (2^16), a minimum block size of 8 (1024 bytes), and a parallelization parameter of 1.
Previous default configuration:
cpuCost=16384, memoryCost=8, parallelism=1
New default configuration:
cpuCost=65536, memoryCost=8, parallelism=1
The default salt length was also updated from 64 to 16.

Use Argon2id with a minimum configuration of 15 MiB of memory, an iteration count of 2, and 1 degree of parallelism.
Previous default configuration:
memory=4, iterations=3, parallelism=1
New default configuration:
