How do you store remember-me tokens safely?
PICTURE THIS: A SENTENCE BECOMES TOKENS
The model does not read letters like humans. It reads these pieces, then predicts the next one.
Simple meaning
Use Identity's stamped tokens that invalidate on password change.
WHY — Security instead of guessing?
Why interviewers care about Security:
question about Security.
trade-offs, and what you would actually do on a .NET MVC project - not buzzwords.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens with tokens?
Before the model can read a sentence, it goes through these steps:
- 1Use Identity's stamped tokens
that invalidate on password change.
- 2Long-lived raw tokens in
cookies are dangerous.
- 3I rotate series identifiers
on each use when implementing custom schemes.
- 4Context mix
Attention looks at nearby tokens together.
- 5Next token
The model scores what should come next.
- 6Decode
IDs turn back into readable text.
EXAMPLE — See it in action
Let's see how a real sentence is tokenized (tokens may vary by model):
Note: Actual tokens and IDs depend on the tokenizer (e.g., GPT, Llama, etc.).
Key takeaway
Use Identity's stamped tokens that invalidate on password change. Long-lived raw tokens in cookies are dangerous.
